Locally Confined Primary Signet Ring Cell Carcinoma of the Prostate with Immunohistochemical Analysis.

A case of locally confined primary signet ring cell carcinoma of the prostate in an 85 years old male with complaints of retention of urine, dysuria and frequent nocturia is reported. On per rectal digital examination, hard nodular prostate of grade 3 enlargement was palpated. Serum prostate specific antigen (PSA) level was 33.7ng/ ml. Chest x-ray and computed tomography of the pelvis was negative for metastatic disease. Hematological and biochemical investigations were within normal limits. Transurethral prostatic biopsy was done and histopathology revealed the diagnosis of poorly differentiated adenocarcinoma. Transurethral resection of prostate (TURP) with bilateral orchidectomy along with radiotherapy was selected as modality of treatment. After histopathological examination of TURP specimen with Haematoxylin and Eosin (H & E) and Periodic acid Schiff (PAS) stain, a diagnosis of primary signet ring cell carcinoma of prostate was given which was confirmed by immunohistochemical analysis.

Postoperative chemoradiation in patients with localized gastric adenocarcinoma: Single center experience.

Background : 5-Flourouracil (FU)-based chemotherapy (CT) and concurrent 45 Gy radiotherapy (RT) is one of the standard postoperative approaches currently used in gastric carcinoma. The high toxicity rates of this treatment leads to interruption of treatment in the majority of patients. In our study, we investigated the rates of toxicity and treatment discontinuation observed during postoperative FU-based chemoradiotherapy (CRT); retrospectively evaluated the effect of CRT and the other prognostic factors on local and distant control and survival. Patients and Methods: A total of 160 patients consisting of 97 total and 63 subtotal gastrectomy receiving postoperative CRT, have been studied retrospectively. Results : Patients who had to discontinue the treatment for a median of 6 (range, 3-13) days experienced toxicity during treatment at a rate of 43%. During the 21 (range, 4-68) months of follow-up local recurrences were observed in 8 (5%) patients and distant recurrences were observed in 41 (25.6%) patients. While the 1-3 year overall survival (OS) rates were 75% and 42%, 13-year disease-free survival (DFS) rates were 63% and 42%, respectively. In the univariate analysis for OS and DFS demonstrated statistical significance for below those 60 years of age, D1-D2 dissection type, negative surgical margin, early treatment beginning, the absence of invasion, and early stage disease. D1D2 dissection type, early treatment begining, age below 60 years and early stage disease significantly improve OS and DFS in multivarite analysis. Conclusions: Survival is worse in patients older than 60 years, had late treatment begining, advanced stage and D0 dissection.
