Tumour Diameter (tumour + diameter)
Selected AbstractsDetection of uveal melanoma by optometrists in the United KingdomOPHTHALMIC AND PHYSIOLOGICAL OPTICS, Issue 4 2001Bertil Damato Summary In the United Kingdom, most uveal melanomas are detected by optometrists. Prospectively collected data on patients with uveal melanoma presenting to optometrists were analysed retrospectively to determine: (a) the proportion of patients who were asymptomatic at the time of tumour detection, (b) the proportion of symptomatic patients reporting that their tumour was missed at their initial presentation and (c) the clinical features related to immediate tumour detection. The 223 patients had a mean age of 59.7 years, a mean tumour diameter of 11.3 mm and a mean tumour thickness of 4.6 mm. Symptoms were present in 122 patients (55%) and were associated with large tumour size (p<0.0001) and male gender (p=0.003), with more males tending to have a large tumour (p=0.004). Seventy-nine percent of symptomatic patients reported that their tumour was detected at their first visit. Failure of tumour detection in symptomatic patients was associated with absence of tumour extension posterior to equator (p<0.0001). [source] SIGNIFICANCE OF TUMOUR VOLUME MEASUREMENTS IN TONGUE CANCER: A NOVEL ROLE IN STAGINGANZ JOURNAL OF SURGERY, Issue 8 2007Min H. Chew Background: Tongue cancers are staged by the American Joint Committee on Cancer and the Union Internationale Contre le Cancer TNM staging systems. Cancer, however, evolves in a 3-D plane. Hence, using the largest tumour diameter will not reflect total cancer volume. We aim to evaluate the use of tongue cancer tumour volume (Tv) as a prognostic predictor of disease recurrence and survival. Methods: The study is a retrospective analysis of patients in Singapore General Hospital who underwent complete resection for histologically proven tongue carcinoma from 2000 to 2002. The Tv was measured on staging T2 -weighted magnetic resonance imaging datasets by semiautomated methods. Results: Seventeen patients with a median follow-up duration of 57.9 months were studied. A wide range of volumes was noted in each T stage. The median time to relapse was 8.6 months for those with Tv , 13 cc but was not achieved for those with Tv < 13 cc. The hazard ratio comparing Tv ,13 cc versus <13 cc is 9.02 (95% confidence interval (CI) 1.70,47.94, P = 0.014). Of the seven deaths reported, five patients had Tv , 13 cc. The median overall survival was 15.8 months for those with Tv , 13 cc but was not achieved for those with Tv < 13 cc. The hazards of death for Tv , 13 cc was 3.91 times that of Tv < 13 cc (95%CI 0.86,17.86, P = 0.078). Conclusion: Tongue cancer Tv measurement allows a more refined and accurate assessment of tumour status. This can be a possible prognostic indicator and be used in a novel staging method for the future. [source] Routine scrotal ultrasonography during the follow-up of patients with testicular cancer leads to earlier detection of asynchronous tumours and a high rate of organ preservationBJU INTERNATIONAL, Issue 8 2010Brigitte Stoehr Study Type , Diagnosis (case series) Level of Evidence 4 OBJECTIVE To compare outcomes of patients with asynchronous tumours detected before and after the introduction of scrotal ultrasonography (SUS) during routine follow-up examinations. PATIENTS AND METHODS Since January 2001 SUS was also used during the follow-up of patients with testicular cancer. A series of 16 consecutive patients with asynchronous bilateral testicular tumours diagnosed while still complying with routine follow up investigations were identified and divided into two groups; group A was diagnosed by palpation only, before 2001, and group B was diagnosed after 2000. The groups were compared statistically for the interval between asynchronous tumours, clinical stage, tumour diameter at the time of diagnosis and rate of testis-sparing surgery. RESULTS All tumours in group A were diagnosed by palpation, but only two in group B were palpable at the time of diagnosis. The mean tumour diameter was statistically significantly smaller in group B (1.2 cm) than in group A (2.68 cm); testis-sparing surgery was used in all of group B and only three patients in group A. After organ-sparing surgery all patients had normal testosterone levels. All patients after organ-sparing surgery had adjuvant scrotal radiotherapy because of germ cell tumour, and no patient had a local recurrence. CONCLUSION Our data indicate that using SUS for the remaining testicle in routine follow-up visits of patients with testicular cancer leads to the earlier detection of smaller tumours and, consequently, a higher rate of organ preservation. The maintenance of physiological endocrine function might finally result in a better quality of life. [source] Pathological tumour diameter predicts risk of conventional subtype in small renal cortical tumoursBJU INTERNATIONAL, Issue 10 2008Melissa A. Laudano OBJECTIVE To examine whether pathological tumour diameter assists in predicting conventional vs other histological subtypes in renal cortical tumours (RCTs) of ,4 cm diameter. PATIENTS AND METHODS In all, 393 patients from Columbia University's Comprehensive Urologic Oncology Database who underwent radical or partial nephrectomy between 1988 and 2005 and had RCTs of ,4 cm were analysed. Logistic regression analysis using tumour diameter as a continuous variable was used to determine whether size predicted histological subtype. Odds ratios (ORs) were calculated to estimate the likelihood of having conventional histology based on diameter. RESULTS The median patient age at surgery was 64.3 years and median tumour diameter was 3 cm, In all, 256 (65.1%) of the RCTs were conventional subtype and 137 (34.9%) were nonconventional. Logistic regression analysis showed that for every 1 cm increase in diameter up to 4 cm, the RCT was 1.27 times more likely to be conventional (P = 0.020). The ORs showed that a 4-cm RCT was 2.06 times more likely to be conventional than tumours of 0.6,1.5 cm. CONCLUSION There was a positive association between RCT diameter and the risk of having conventional renal cell carcinoma (RCC). Given that RCC histological subtype is a prognostic indicator for outcome, these findings may be applied in the selection of treatment options. Further studies investigating tumour size and other variables predictive of tumour histology will help clinicians better predict the RCC subtype. [source] Relation of microvessel density with microvascular invasion, metastasis and prognosis in renal cell carcinomaBJU INTERNATIONAL, Issue 6 2008Esin Yildiz OBJECTIVE To clarify the significance of microvessel density (MVD) in a retrospective investigation the relationship between the pattern of MVD (reflecting angiogenesis), and tumour stage, grade, size, and occurrence of microvessel invasion (MVI), metastasis, and cancer-specific survival (CSS) in patients who had surgery for renal cell carcinoma (RCC). PATIENTS AND METHODS Vessels were labelled in sections of formalin-fixed, paraffin-embedded tissues from 54 RCCs by CD34 immunohistochemistry. The mean MVD, expressed as the number of vessels per 10 high-power fields (HPF, ×400) were measured for each case. In addition, all pathological slides were reviewed for the presence and absence of MVI. The prognostic value of MVD and MVI was then evaluated, and correlated with the usual prognostic variables, tumour metastasis and CSS. RESULTS In a univariate analysis of CSS, the MDV tended to be lower as stage increased from pT1 to pT3, and as grade increased from G1 to G4, although it was statistically significant only for stage (P < 0.001 and 0.050, respectively). The mean MVD was higher in 42 nonmetastatic than in 12 metastatic tumours, and in 33 tumours associated with MVI than in 21 with no MVI (P < 0.001). The mean MVD was also lower and significantly different for 28 large than 26 small tumours (P = 0.005). The survival rate of patients with tumours that were small, low-stage, of higher MVD, with no MVI and metastasis was significantly higher than that of patients with large, high-stage, low MVD, with MVI and metastatic tumours (all P < 0.001). MVI was significantly more common with a decreasing trend in MVD and the presence of metastasis (Spearman rank correlation rs = ,0.68, P = 0.01, and rs = 0.39, P = 0.01, respectively). Independent prognostic factors in a multivariate analysis were: in all patients with RCC, tumour stage (P = 0.013) and metastasis (P = 0.028); in those with low MVD, MVI (P = 0.004) and metastases (P = 0.016); in those with no MVI, stage (P = 0.020); in those with MVI, MVD (P = 0.001); in those with no metastases, stage (P = 0.045); and in those with metastases, MVD (P < 0.001). No independent predictor was identified in patients with high MVD. In patients with no metastases there was a significantly shorter median CSS time in RCCs with low MVD and with MVI (P = 0.004 for both). Similarly, patients who had grade 3,4 tumours, vs those with lower MVD and with MVI, had a significantly shorter median CSS (P = 0.020 for MVD, and 0.01 for MVI). CONCLUSIONS This study suggested that MVD in RCC was inversely associated with MVI, tumour metastasis, patient survival and tumour diameter and stage, from the usual prognostic variables, but MVD was not an independent prognostic factor in multivariate analysis for all patients with RCC. Low MVD and the presence of MVI appears to be a marker for identifying patients with an adverse prognosis. [source] Laparoscopic radical nephrectomy for T1 renal cancer: the gold standard?BJU INTERNATIONAL, Issue 1 2004A comparison of laparoscopic vs open nephrectomy OBJECTIVE To evaluate the complication rate and clinical follow-up of patients treated for T1 renal cancer by open or laparoscopic nephrectomy at the same institution, as this approach appears to be attractive for treating small renal cancers. PATIENTS AND METHODS Between 1995 and 2002, 39 patients underwent retroperitoneal laparoscopic and 26 transperitoneal open radical nephrectomy for T1 renal cancer (TNM 1997). Variables before during and after surgery, e.g. cancer recurrence, were compared between the groups. RESULTS There were no differences between the laparoscopic and open groups in age, sex ratio, weight, height, fitness score, operative duration (134 vs 133 min), minor or major complications, tumour diameter, Fuhrman grade or length of follow-up. Patients who underwent laparoscopic surgery had less blood loss (133 vs 357 mL, P < 0.001), less need for transfusion (none vs 150 mL, P = 0.04), a lower consumption of analgesia drugs, and shorter hospitalization (5.5 vs 8.8 days, P < 0.001). With a mean follow-up of 20.4 months there was no recurrence or tumour progression. CONCLUSION Laparoscopic radical nephrectomy for patients with T1 renal cancer is a safe, reliable procedure that decreases hospitalization time and bleeding, and ensures the same cancer control as open nephrectomy. [source] A predictive model for local recurrence after transanal endoscopic microsurgery for rectal cancer,,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 3 2009S. P. Bach Background: The outcome of local excision of early rectal cancer using transanal endoscopic microsurgery (TEM) lacks consensus. Screening has substantially increased the early diagnosis of tumours. Patients need local treatments that are oncologically equivalent to radical surgery but safer and functionally superior. Methods: A national database, collated prospectively from 21 regional centres, detailed TEM treatment in 487 subjects with rectal cancer. Data were used to construct a predictive model of local recurrence after TEM using semiparametric survival analyses. The model was internally validated using measures of calibration and discrimination. Results: Postoperative morbidity and mortality were 14·9 and 1·4 per cent respectively. The Cox regression model predicted local recurrence with a concordance index of 0·76 using age, depth of tumour invasion, tumour diameter, presence of lymphovascular invasion, poor differentiation and conversion to radical surgery after histopathological examination of the TEM specimen. Conclusion: Patient selection for TEM is frequently governed by fitness for radical surgery rather than suitable tumour biology. TEM can produce long-term outcomes similar to those published for radical total mesorectal excision surgery if applied to a select group of biologically favourable tumours. Conversion to radical surgery based on adverse TEM histopathology appears safe for p T1 and p T2 lesions. Copyright © 2009 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd. [source] Importance of tumour size in papillary and follicular thyroid cancer,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 2 2005C. Passler Background: The most controversial change in the new pathological tumour node metastasis (pTNM) classification of thyroid tumours is the extension of the pT1 classification to include tumours up to 20 mm. Methods: Four hundred and three patients with pT1 or pT2 differentiated thyroid carcinomas were divided into three groups according to tumour diameter (group 1, 10 mm or less; group 2, 11,20 mm; group 3, 21,40 mm). They were analysed retrospectively with respect to carcinoma-specific and disease-free survival. Results: No patient in group 1 died from papillary thyroid carcinoma, compared with three patients in group 2 and six in group 3. There was a statistically significant difference in carcinoma-specific survival between groups 1 and 2 (P = 0·033). Two patients in group 1, six in group 2 and eight in group 3 developed recurrence. The difference in disease-free survival between groups 1 and 2 was significant (P = 0·025). One patient in group 1, three in group 2 and four in group 3 died from follicular thyroid carcinoma, but there were no significant differences in survival between the three groups. Conclusion: Extension of the pT1 classification to cover all tumours up to 20 mm does not appear to be justified for papillary thyroid carcinoma.

[source] Factors predictive of 5-year survival after transarterial chemoembolization for inoperable hepatocellular carcinoma,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 3 2003C. B. O'Suilleabhain Background: Transarterial chemoembolization (TACE) is widely used for unresectable hepatocellular carcinoma (HCC), but the long-term survival benefit remains unclear. Methods: Pretreatment variables were analysed for factors predictive of actual 5-year survival from a prospective database of patients with inoperable HCC treated by TACE between 1989 and 1996. Results: Complete 5-year follow-up (median 91 months) was obtained for 320 patients who underwent a median of 4 (range 1,41) TACEs. Median tumour size was 9 (range 1,28) cm. There were 25 5-year survivors (8 per cent), including eight with tumours larger than 10 cm in diameter and three with portal vein branch involvement. On univariate analysis, female gender (P = 0·037), absence of ascites (P = 0·028), platelet count below 150 ×109 per litre (P = 0·011), albumin concentration greater than 35 g/l (P = 0·04), ,-fetoprotein level below 1000 ng/ml (P = 0·007), unilobar tumour (P = 0·027), fewer than three tumours (P = 0·015), absence of venous invasion (P = 0·011), and tumour diameter less than 8 cm (P = 0·021) were significant predictors of 5-year survival. Albumin concentration greater than 35 g/l (P = 0·011), unilobar tumour (P = 0·012) and ,-fetoprotein level below 1000 ng/ml (P = 0·014) were independent prognostic factors on multivariate analysis. Conclusion: Five-year survival is possible with TACE for inoperable HCC, even in some patients with advanced tumours. Unilobar tumours, ,-fetoprotein level below 1000 ng/ml and albumin concentration greater than 35 g/l were factors predictive of 5-year survival.

[source] Long-term prognosis of children with papillary thyroid cancer presenting with pulmonary metastasesBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 9 2000J. Brink Background Papillary thyroid cancer (PTC) has a generally favourable prognosis, but elderly patients with distant metastases or extracapsular invasion fair poorly. In small studies with short follow-up, young patients presenting with such extracapsular invasion and pulmonary metastases have faired well. This retrospective study was undertaken to clarify the long-term prognosis of such patients with advanced PTC. Methods Twenty-one children and young adults (median age 14 (range 6,20) years) presenting with PTC and pulmonary metastases were treated at a single institution between 1947 and 1998. Mean maximal tumour diameter was 4·65 cm. Initial surgical treatment consisted of total thyroidectomy (n = 16), subtotal thyroidectomy (n = 4) and isthmectomy (n = 1), coupled with a variety of lymph node dissections (n = 20). After operation, 19 patients were treated with ablative and incremental doses of iodine-131 until disease free. All patients were placed on suppressive thyroid hormone after operation. Mean length of follow-up was 21 years (range 3 months to 47 years). Follow-up was less than 3 years in four patients. All patients have undergone post-treatment radionucleotide and radiological evaluation. Results Nine of the 21 patients developed recurrent disease. The risk of recurrence at 5 years was 39 (95 per cent confidence interval 14,57) per cent. Eight had cervical lymph node recurrence and no patient developed recurrent pulmonary disease. All patients with identifiable recurrent disease underwent selective lymph node resection, which involved multiple resections in four. At follow-up, 18 patients remain completely free of disease, one patient has recurrent cervical node disease and two patients have died. The disease-free survival at 5 years was 95 (95 per cent confidence interval 86,100) per cent. Cause-specific death occurred in a single patient who died from extensive local disease at age 29 years after 12 years of multiple cervical lymph node recurrences. Conclusion A stepwise treatment approach including total thyroidectomy, high-dose iodine-131 treatment and early surgical reintervention for suspected local recurrent disease allows long-term survival and frequent ,cure' for young patients with PTC and concomitant pulmonary metastases. © 2000 British Journal of Surgery Society Ltd [source] Does delayed treatment shorten the life of patients with fatal choroidal melanoma?ACTA OPHTHALMOLOGICA, Issue 2009B DAMATO Purpose Metastatic death from uveal melanoma occurs in about 50% of patients many of whom experience a delay in treatment, either intentionally or accidentally. The aim of this study was to determine whether treatment delay shortens survival in patients with choroidal melanoma whose disease apparently proved fatal. Methods Patients with choroidal melanoma were included in the study if resident in mainland Britain and if deceased. Survival was analysed according to basal tumour diameter by Kaplan-Meier and Log rank analysis. Results A total of 696 patients with choroidal melanoma died. The patients had a median age of 65 years and a median basal tumour diameter of 15.0 mm. The basal tumour diameter was <10mm in 41 patients; 10-11mm in 88; 12-13mm in 108; 14-15mm in 165; 16-17mm in 123; and >17mm in 171 patients. Log-rank analysis showed no correlation between survival and basal tumour diameter in these patients (Log rank analysis, p = 0.5537). There was perhaps a trend towards longer survival in patients with a basal tumour diameter less than 10mm. Conclusion In patients with fatal uveal melanoma, there is no significant correlation between basal tumour diameter and survival time. Delay in treatment does not seem to worsen prognosis for survival significantly, except perhaps in patients with small tumours. This finding adds further support to the concept that the main objective of ocular treatment is to conserve the eye with as much useful vision as possible. Since ocular treatment can itself cause significant visual loss, the benefit of treating asymptomatic uveal melanomas is uncertain. There is scope for randomized, prospective studies of treatment versus non-treatment of patients with asymptomatic choroidal melanoma. [source] Mortality after uveal and conjunctival melanoma: which tumour is more deadly?ACTA OPHTHALMOLOGICA, Issue 2 2009Emma Kujala Abstract. Purpose:, We aimed to model and compare mortality rates for uveal melanoma (UM) and conjunctival melanoma (CM) by adjusting for differences in tumour size and local recurrence. Methods:, Population-based mortality data for 240 and 85 patients with primary UM and CM and 91 and 23 patients with disseminated UM and CM, respectively, were compared with cumulative incidence analysis. Cox proportional hazards multivariate regression with time-dependent variables was used to adjust for differences in tumour diameter, thickness and recurrence rates. Results:, The 10-year cumulative incidences of metastatic death from UM and CM were 39% (95% confidence interval [CI] 33,45) and 32% (95% CI 21,44), respectively. After adjusting for tumour size, risk of death from CM was higher than from UM (hazard ratio [HR] 1.9; p = 0.039). Additional adjustment for more frequent local recurrence of CM diminished the difference (HR 1.5; p = 0.25). Survival periods after systemic metastasis of UM and CM were comparable (median 8 months). Conclusions:, Clinical observations show longer survival after primary CM than after primary UM. This reflects the smaller average size of CM. However, a primary CM of a given size is more deadly than a UM of equivalent size because primary CM tends to recur after treatment and, possibly, because additional lymphatic dissemination occurs with CM. [source] Ocular conservation in patients with uveal melanoma by a multimodality approach to treatmentACTA OPHTHALMOLOGICA, Issue 2007C GARCIA-ALVAREZ Purpose: To analyse eye survival in patients with uveal melanoma with a multimodality approach to treatment Methods: 273 patients with uveal melanoma diagnosed at Ocular Oncology Unit of the University Hospital of Valladolid from 1997 September to 2007 April. Pearson's Chi-square test was used to identify between variables and primary enucleation. Logistic regression was used to identify independent variables predicting primary enucleation. Cox's univariate proportional hazards model was used to identify associations between variables and time to secondary enucleation.Kaplan-Meier estimates were used to draw survival curves for time to secondary enucleation Results: 273 patients were included in the study. Primary enucleation was performed in 80 patients. Secondary enucleation in 12. Gender (p=0,032), basal tumour diameter >15mm (p<0,001), tumour weight >10mm (p<0,001), anterior tumour margin (p<0,001) and extraocular spread (p<0,001) were associated with primary enucleation. Predictive factors for primary enucleation were largest basal tumor diameter (odds ratio [OR], 3,8; 95% confidence interval [IC], 1,5-9,1) and tumour weight (OR, 2,7; IC, 1-7,5). Ocular conservation probability 5 years after conservative treatment was 88%. Largest basal tumor diameter, anterior tumour margin and extraocular spread had influence in ocular survival after conservative treatment. Only largest basal tumor diameter was a predictive factor of secondary enucleation Conclusions: In the present series 69,9% of patiens had a conservative treatment and 88% of them conserved treated eye 5 years [source] Primary tumour diameter as a risk factor for advanced disease features of differentiated thyroid carcinomaCLINICAL ENDOCRINOLOGY, Issue 2 2009Frederik A. Verburg Summary Objective, To study the relationship between primary tumour size and the risk of advanced disease features (multifocal or locally invasive disease, lymph-node or distant metastases) in differentiated thyroid carcinoma (DTC). Design, A retrospective chart review study. Patients, The study sample comprised 935 papillary (PTC) and 291 follicular thyroid carcinoma (FTC) patients treated in our hospital from 1978 to 2007. Measurements, Kaplan,Meier analyses and log-rank tests were performed to calculate tumour size-adjusted cumulative risk of advanced disease features. Results, Accounting for primary tumour diameter, there were no significant differences in cumulative risks of multifocal carcinoma (P = 0·12) or distant metastases (P = 0·49) between PTC and FTC. PTC showed higher cumulative risks of local invasion (P < 0·0001) or lymph-node metastases (P < 0·0001). The cumulative risk of tumour multifocality increased 5%/cm of primary tumour diameter. The cumulative risk of local invasion or lymph-node metastases in PTC and of distant metastases in DTC increased exponentially at a threshold tumour diameter of 10 mm. In FTC, lymph-node metastases are associated almost exclusively with primary tumours showing extrathyroidal growth. Conclusions, Starting with a 1 cm primary tumour diameter, increasing tumour size is associated with an exponentially increasing risk of local invasion or lymph-node or distant metastases of DTC. The current classification of carcinomas < 2 cm as T1 is therefore questionable. [source] Clinical and biochemical characteristics of normotensive patients with primary aldosteronism: a comparison with hypertensive casesCLINICAL ENDOCRINOLOGY, Issue 1 2008Virginie Médeau Summary Objective, It is unknown why some patients with biochemical evidence of primary aldosteronism (PA) do not develop hypertension. We aimed to compare clinical and biochemical characteristics of normotensive and hypertensive patients with PA. Design and patients, Retrospective comparison of 10 normotensive and 168 hypertensive patients with PA for office or ambulatory blood pressure, serum potassium, plasma aldosterone and renin concentrations; the aldosterone : renin ratio, and tumour size. Comparison of initial hormonal pattern and drop in blood pressure following adrenalectomy in five normotensive and nine hypertensive patients matched for age, sex and body mass index. Results, The 10 normotensive patients were women and presented with hypokalemia or an adrenal mass. Age, plasma aldosterone and renin concentrations were similar in normotensive and hypertensive cases, but kalemia and body mass index were significantly lower in the normotensive patients. Mean tumour diameter was larger in the normotensive patients than in the hypertensive matched patients with an adenoma (P < 0·01). In normotensive patients, diastolic blood pressure and upright aldosterone correlated negatively with kalemia. Blood pressure was lowered similarly after adrenalectomy in five normotensive PA patients and in their matched hypertensive counterparts. Aldosterone synthase expression was detected in four out of five adrenal tumours. Conclusions, Blood pressure may be normal in patients with well-documented PA. The occurrence of hypokalemia, despite a normal blood pressure profile, suggests that protective mechanisms against hypertension are present in normotensive patients. [source] Posterior pelvic exenteration for primary rectal cancerCOLORECTAL DISEASE, Issue 4 2006G. C. Bannura Abstract Background, Indications for and the prognosis of posterior pelvic exenteration (PPE) in rectal cancer patients are not clearly defined. The aim of this study was to analyse the indications, complications and long-term results of PPE in patients with primary rectal cancer. Methods, A retrospective review included patient demographics, tumour and treatment variables, and morbidity, recurrence, and survival statistics. These results were compared with a group of female patients who underwent standard resection for primary rectal cancer in the same period (non PPE group). Results, The series included 30 women with an average age of 56.7 years (range 22,78). Tumour location was recorded in three cases in the upper rectum, 13 cases in the medium rectum and 14 cases in the lower rectum. A sphincter-preserving procedure was performed in 70% of the patients. Mean operative time was 4.2 h (range 2,7.5 h). Overall major morbidity rate in this series was 50% and mean hospital stay was 19.7 days (range 9,60 days). There was no hospital mortality. Pathological reports showed direct invasion of uterus, vagina or rectovaginal septum in 19 cases, involvement of perirectal tissue in 25 cases and positive lymph nodes in 18 cases. Comparison between PPE and non PPE groups showed no differences in mean tumour diameter, histological grade and tumour stage, but patients in the first group were younger. Although low tumours were seen more frequently in the PPE group (P = 0.003), the rate of sphincter-preserving procedure was comparable in both groups. Operative time was longer (P = 0.04) and morbidity was higher (P = 0.0058) in the PPE group. Local recurrence with or without distant metastases for the whole series was 30%. Five-year survival rate for patients who underwent curative resections (TNM I,III) was 48% in the PPE group vs 62% in the non PPE group (P = 0.09). Conclusions, In the present series, PPE prolonged operative time, increased postoperative complications and showed a trend toward poor prognosis in recurrence and survival. However, PPE offers the only hope for cure to patients with a primary rectal cancer that is adherent or invades reproductive organs. [source] | ||||||||||
