    Adjuvant radiation therapy is associated with improved survival for gallbladder carcinoma with regional metastatic disease

    JOURNAL OF SURGICAL ONCOLOGY, Issue 1 2007
    Pablo Mojica MD
    Abstract Background Gallbladder carcinoma is a rare malignancy and is associated with dismal outcomes. The aim of this study was to better define the role of adjuvant radiation therapy in the management of gallbladder carcinoma. Methods The Surveillance, Epidemiological, and End Results (SEER) survey from the National Cancer Institute was queried from 1992 to 2002. Retrospective analysis was done. The end-point of the study was overall survival. Results There were a total of 3,187 cases of gallbladder carcinoma in the registry from 1992 to 2002. Of the surgical group, 35% were stage I, 36% were stage II, 6% were stage III, and 21% were stage IV. Adjuvant radiation was used in 17% of the cases. The median survival for those patients receiving adjuvant radiation therapy was 14 months compared to an 8 months median survival for those treated without adjuvant radiation therapy (P,,,0.001). The survival benefit associated with radiation use was only presenting those patients with regional spread (P,=,0.0001) and tumors infiltrating the liver (P,=,0.011). Conclusion The use of adjuvant radiation therapy is associated with improved survival in patients with locally advanced gallbladder cancer or gallbladder cancer with regional disease. J. Surg.

    Response to intraarterial induction chemotherapy: A prognostic parameter in oral and oropharyngeal cancer

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 8 2006
    Adorján F. Kovács MD
    Abstract Background. Patients with head and neck cancer and good pathologic response to neoadjuvant systemic induction chemotherapy have a better prognosis for survival than do those with stable or progressive disease. Thus, induction chemotherapy could theoretically help in stratifying further treatment, but toxicity is much too high. The prognostic implication of superselective intraarterial high-dose cisplatin administered by a femoral approach, which has much less toxicity, is not yet known. Methods. One hundred eighty-seven unselected consecutive patients with previously untreated oral and oropharyngeal squamous cell carcinoma received intraarterial high-dose cisplatin for induction and were assessed for response by visual examination and palpation. This treatment was followed by surgery and adjuvant radiation with concomitant systemic chemotherapy. Omission of a modality depended on individual contraindications and not on preselection. The consequence of omissions has been the constitution of several treatment arms. The overall and disease-free survival in relation to clinical local response after intraarterial induction chemotherapy was calculated using the Kaplan,Meier method. Additional analysis excluded bias caused by stages and treatment arms. Results. Explorative statistics using the log-rank and chi-square tests demonstrated a strong prognostic relevance of response to intraarterial chemotherapy irrespective of stage and treatment. Conclusions. Our results are encouraging for prospective randomized studies and molecular genetic investigations with intraarterial chemotherapy. © 2006 Wiley Periodicals, Inc. Head Neck, 2006 [source]


    Primary sarcoma of the breast

    Abstract Background and Objectives Primary sarcoma occurring in breast is rare and comprises 0.5,1% of all breast neoplasm. Majority of the series include both stromal and cystosarcoma phyllodes, only a few hundred cases of sarcomas other then cystosarcoma are reported. Patients and Methods We carried out a retrospective analysis of 19 patients with primary sarcoma of the breast treated between 1982 and 2002. Results Mean age of the patients was 38.6 years (12,70 years). Gradually progressive swelling was the commonest presenting feature. There were eight cases of angiosarcoma, four cases of spindle cell sarcoma, two each of pleomorphic sarcoma and stromal sarcoma, and one each of malignant fibrous histiocytoma, embryonal rhabdomyosarcoma, and sarcoma (NOS). Eight of these were high-grade (42%). Eight patients underwent either radical or modified mastectomy, three underwent wide excisions, and one underwent quadrantectomy. Ten (52.6%) patients received postoperative adjuvant radiation. Two patients received chemotherapy. After a mean follow-up time of 34.5 months (median 25 months), eight patients failed. Failure was local in five, opposite breast in one, and both local and distant in two. The disease free survival at 3-year was 39%. In univariate analysis only the margin of first surgery was found to be a significant predictor of survival (P,=,0.05). Conclusions Primary sarcomas of the breast are aggressive tumors. Surgical treatment should consist of at least simple mastectomy. All attempts should be made to achieve a negative margin as this appears to be the only factor influencing survival in these patients.

    Evidence supports adjuvant radiotherapy in selected patients with rectal cancer

    ANZ JOURNAL OF SURGERY, Issue 3 2004
    Peter Gibbs
    Background: Much recent data have been published on the risk of local recurrence (LR) following curative surgery for rectal cancer and the impact of adjuvant radiation therapy (RT). With improvements in surgical technique apparently reducing the risk of LR, the relevance of older data upon which the current recommendations for adjuvant RT are based has been questioned. Methods: A focused review was undertaken of the published literature on the risk of LR following surgery for rectal cancer and the impact of adjuvant radiation. In particular the authors attempt to define how accurately the risk for an individual patient can be predicted, trends in reported LR rates over the time period of randomized trials, and the relevance of changing surgical and RT techniques. Results: Many of the perceived differences in published results can be explained by variations in study entry criteria, length of follow up and data recording. Comparisons between studies are most accurate when defined subsets of patients, such as those with stage III disease, followed for the same period of time, are considered. In parallel with improvements in surgical technique, which may have reduced the risk of LR, modifications to RT delivery have resulted in recent series not reporting an increased mortality in those patients treated with modern RT techniques. Conclusion: All of the available evidence supports the use of adjuvant RT in selected patients with rectal cancer. Ongoing studies will better define individual patient risk and the risk,benefit ratio of adjuvant RT. [source]


    Interdigitating dendritic cell sarcoma of the tonsil

    ASIA-PACIFIC JOURNAL OF CLINICAL ONCOLOGY, Issue 3 2010
    Sun Young KIM
    Interdigitating dendritic cell sarcoma (IDCS) is an extremely rare malignancy derived from antigen-presenting cells, with 55 cases reported thus far. A standard treatment modality is still being debated. This report describes a 56-year-old female who presented with right tonsillar enlargement and right submandibular swelling for 6 months. Treatment with empiric antibiotics did not result in improvement of her symptoms. Fine needle aspiration of the tonsil revealed no malignant cells. Tonsillectomy was eventually performed due to persistent symptoms. Based on microscopic findings, immunohistochemical stains, and review of the literature, the present case was finally diagnosed as IDCS of the tonsil with cervical lymph node involvement. The patient received four cycles of CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) chemotherapy, and a clinically complete response was achieved followed by adjuvant radiation.

    Abstract Objective: The aim of this study was to review cases of extra-pulmonary small cell carcinoma (EPSCC), including their clinical manifestations and treatment outcomes. Methods: We retrospectively reviewed the medical records and pathological reports of patients who were diagnosed with EPSCC from 1998 to 2005. Results: Overall 21 EPSCC patients were eligible for this study. The most common primary sites were the gastrointestinal organs and the nasal cavity. Eleven patients (52.3%) had limited disease (LD) and 10 patients (47.7%) had extensive disease (ED). Nine patients underwent radical surgery alone, four received only radical radiation and two received only palliative chemotherapy. Two patients received adjuvant radiation or chemotherapy following surgical resection and one received a combination of all three treatment modalities. Three patients declined specific treatment and were treated with best supportive care. The median overall survival in the ED group was only 3 months (range 1,16 months), compared to 30 months (range 20,61 months) for LD. EPSCC of pancreas demonstrated a favorable clinical outcome with treatment, whereas primary EPSCC of the liver, esophagus and rectum had an aggressive natural history and a poor response to treatment. Conclusion: Our report suggests that EPSCC may have a different biology from that of pulmonary small cell carcinoma. When detected at an early stage, EPSCC may have an excellent prognosis with treatment. Additional studies involving more patients with EPSCC are warranted to further define the optimal roles of each treatment modality. [source]


    An unrandomized prospective comparison of urinary continence, bowel symptoms and the need for further procedures in patients with and with no adjuvant radiation after radical prostatectomy

    BJU INTERNATIONAL, Issue 4 2003
    T. Hofmann
    OBJECTIVE To prospectively assess, using a questionnaire-based study, the relative differences and changes in urinary continence and bowel symptoms, and the need for further surgery, within the first year after radical retropubic prostatectomy (RRP) in patients with and with no adjuvant radiotherapy (aRT). PATIENTS AND METHODS The study included 96 men with clinically organ-confined adenocarcinoma of the prostate who underwent RRP between March 1998 and June 1999. A subset of 36 patients was recommended aRT of the prostatic fossa (median dose 54 Gy) because of positive surgical margins and/or seminal vesicle involvement. Using a mailed questionnaire all patients were prospectively assessed at 4-month intervals for the first year after RRP. RESULTS Valid data were analysed from 83 patients (overall response rate 86%), of whom 30 (36%) had received aRT. At 4 months a significantly lower proportion used no pads and significantly more used 1 pad/day in the aRT than in the RRP group (both P < 0.05). Eight and 12 months after RRP there was no statistically significant difference between the groups in urinary incontinence. However, 53% of men in the aRT group had stool urgency and 13% reported fecal incontinence at 4 months, compared with 1.9% and none (both P < 0.01) of the RRP group. At 1 year after RRP bowel symptoms and fecal continence improved in the aRT group and there was no significant difference for these symptoms between the groups. Starting aRT early (, 12 weeks after RP) or late (> 12 weeks) had no significant effect on urinary continence, bowel symptoms and fecal incontinence. Apart from dilatation of urethral strictures in one patient in each group, no further procedures were reported during the follow-up. CONCLUSION A moderate dose of aRT after RRP had a temporary effect on subjective urinary continence at 4 months but not at 8 and 12 months. More patients receiving aRT reported significant bowel symptoms at 4 and 8 months than those with RRP only, but at 1 year most of these symptoms had resolved and there were no significant differences between the groups.

    Prospective analysis of carotid artery flow in breast cancer patients treated with supraclavicular irradiation 8 or more years previously,

    CANCER, Issue 2 2008
    No increase in ipsilateral carotid stenosis after radiation noted
    Abstract BACKGROUND. To the authors' knowledge, the effects of supraclavicular fossa radiation on the carotid artery are not well described. In the current study, the authors performed a prospective study to examine the long-term risk of carotid artery stenosis after supraclavicular irradiation for breast cancer. METHODS. A total of 46 breast cancer patients who were treated with adjuvant radiation to the supraclavicular fossa with >8 years of follow-up underwent bilateral Doppler imaging of the carotid artery. Two independent cardiologists interpreted each ultrasound study with no knowledge of which side was treated. RESULTS. The median follow-up from the date of diagnosis was 14.6 years and the mean patient age at the time of ultrasound was 55 years. The median prescribed dose to the supraclavicular fossa was 50 grays. Four patients were found to have clinically relevant, asymptomatic carotid stenosis, for which a cardiology referral was necessary. Only 1 of these 4 patients had stenosis involving the irradiated carotid artery only; 1 patient had bilateral stenosis and 2 patients had only contralateral stenosis. There was no difference noted with regard to isolated ipsilateral versus contralateral medial intimal thickening of the carotid artery (5 patients vs 6 patients, respectively). Furthermore, there were no differences noted with regard to ipsilateral versus contralateral peak systolic flow in the internal (83.5 vs 85.6 cm/seconds; P = .522 by the Student t test and P = .871 by the signed rank test) or common (74.4 vs 77.0 cm/seconds; P = .462 by the Student t test and P = .246 by the signed rank test) carotid artery. CONCLUSIONS. In this prospective study of breast cancer patients with long follow-up, there was no evidence of late, clinically relevant stenosis, increased intimal thickening, or increased peak systolic carotid artery flow secondary to supraclavicular irradiation.
