Risk factors for lymph node metastasis in clinically node-negative penile cancer patients

INTERNATIONAL JOURNAL OF UROLOGY, Issue 4 2009
Aravind Ramkumar
Objectives: To analyze the effects of pathological T stage, grade, extent of surgery for primary tumor, and age group on the risk of developing lymph node metastasis in clinically node-negative penile cancer patients. Methods: We performed a retrospective analysis of 200 clinically node-negative penile cancer patients who were kept under surveillance, after treatment of the primary tumor in our institution. The primary outcome parameter was cytologically or histologically proven lymph node metastasis. Logistic regression analysis was used to compute odds ratios in univariate and multivariate settings. Results: Lymph node metastasis occurred in 31 patients at a median time of three months. Histological grade 3 and grade 2 tumors had a statistically significant increased odds ratio for lymph node metastasis, (7.1[P < 0.001] and 2.7 [P = 0.04], respectively), compared with grade 1 tumors. Although increasing pT stage was associated with increasing odds ratios, the differences were not statistically significant. Nor did the extent of surgery of the primary tumor or the age group significantly influence the risk of developing lymph node metastasis. Conclusions: Histological grade is the most significant parameter influencing the risk of lymph node metastasis in clinically node-negative penile cancer patients on surveillance. Patients with grade 3 and grade 2 tumors may benefit from elective inguinal lymphadenectomy. [source]

Impact of thrombocytosis and C-reactive protein elevation on the prognosis for patients with renal cell carcinoma

Aim: C-reactive protein (CRP) elevation is reportedly a prognostic factor in patients with renal cell carcinoma (RCC). Thrombocytosis has recently been reported also to be a prognostic factor in RCC and, like CRP, to be related to inflammatory cytokines such as interleukin-6. The aim of this study was to evaluate the importance of both thrombocytosis and CRP elevation in tumor recurrence and prognosis for patients with RCC. Methods: The clinical records of 178 patients who underwent radical nephrectomy were reviewed. Thrombocytosis was defined as a platelet count ,350 000/mm3, and CRP elevation was defined as a CRP level ,1.0 mg/dL. Disease-free survival and cause-specific survival rates were calculated. Independent predictors for recurrence and prognosis were determined. Results: Patients with thrombocytosis and patients with elevated CRP levels had significantly higher pathological T stage, clinical stage, tumor size, histological grade, and percentage of microvascular invasion than did patients without THC and patients with CRP levels <1.0 mg/dL, respectively. There was a significant correlation between platelet counts and CRP levels. Multivariate analysis showed that distant metastasis, tumor size, grade 3 components, and CRP elevation were independent predictors for prognosis but thrombocytosis was not. In N0M0 RCC patients, tumor size, microvascular invasion, and CRP elevation were independent predictors for recurrence. CRP elevation and tumor size were independent predictors for prognosis. Conclusions: Platelet count and CRP level are strongly correlated in patients with RCC, but only CRP elevation is an independent predictor for recurrence and prognosis. [source]

Prognostic factors in the surgical treatment of patients with oral carcinoma

Abstract The aim of the study was to analyse the clinical outcome of patients treated surgically for oral carcinoma. A retrospective cohort study was undertaken of 356 patients with oral cavity cancer whose clinicopathological information had been collected prospectively onto a dedicated head and neck database. Disease recurrence and survival were assessed. Neck metastases occurred in 42% of patients. Tumour thickness (both 2 and 5 mm) predicted the presence of nodal metastases. Both pathological T stage (P < 0.001) and tumour thickness cut-off of 5 mm (P = 0.03) were independent predictors of disease-specific survival. With a median follow up of 41 months, overall survival at 5 years was 59% and disease-specific survival was 73%. Patients with thick tumours have a high risk of nodal metastases and this supports the liberal use of elective selective neck dissection in patients with clinically negative necks. [source]

Rectal cancer in young adults: a series of 102 patients at a tertiary care centre in India

Abstract Objective, Rectal cancer in young patients is uncommon. There is little information on rectal cancer in young adults in India. The aim of this study was to determine the relative incidence of rectal cancer in young patients in India and identify any differences in histological grade and pathological stage between younger and older cohorts. Method, All adult patients presenting at a tertiary colorectal unit with primary rectal adenocarcinoma between September 2003 and August 2007 were included. Patients were divided into two groups: 40 years and younger, and older than 40 years. Details regarding patient demographics, preoperative assessment, management and tumour grade and stage were obtained from a prospectively maintained database. Results, One hundred and two of 287 patients (35.5%) were 40 or younger at presentation. Younger patients were more likely to present with less favourable histological features (52.0%vs 20.5% (P < 0.001)) and low rectal tumours (63.0%vs 50.0%) (P = 0.043), but were equally likely to undergo curative surgery compared to the older group (P = 0.629). Younger patients undergoing surgery had a higher pathological T stage (T0,2 18.9%, T3 62.3%, T4 19.7%vs 34.5%, 56.0%, 9.5%) (P = 0.027) and more advanced pathological N stage (N0 31.1%, N1 41.0%, N2 27.9%vs 53.4%, 26.7%, 17.2%) (P = 0.014). Conclusion, The relative number of young patients with rectal cancer in this Indian series is higher than figures reported in western populations. The reasons for this are not clear. The histopathological features of rectal tumours in young patients in this study are consistent with similar studies in Western populations. [source]
