    Intramural Component of Venous, Lymphatic, and Perineural Invasion in Colon Cancer: A Threat or an Illusion?
    (GALENOS PUBL HOUSE, 2022-01-01) Ozer, Leyla; Tasci, Elif Senocak; Mutlu, Arda Ulas; Piyade, Betul; Ramoglu, Nur; Ajredini, Mirac; Gurleyik, Damla; Cecen, Recep; Dincer, Sena Nur; Musevitoglu, Turan; Goksel, Suha; Ince, Umit; Kayhan, Cavit Kerem; Erdamar, Sibel; Yildiz, Ibrahim; Aytac, Erman
    Background: Extramural venous invasion is an independent predictor of poor outcome in colorectal cancer, whereas the significance of the intramural component of venous and lymphatic and perineural invasion is unclear. Aims: To evaluate the prognostic impact of intramural components for venous, lymphatic, and perineural invasions and the relation of these invasion patterns with clinicopathological features in patients with colon cancer. Study Design: A retrospective cross-sectional study. Methods: The analysis included 626 patients with colon cancer in stages II and III. All patients were divided into four categories (no invasion, intramural invasion only, extramural invasion only, or both intramural and extramural invasions) for vascular invasion, lymphatic invasion and perineural invasion. The primary outcomes were 5-year disease-free and overall survival. Results: Right-sided (for vascular invasion, 24.7\% vs. 33.9\%, p = 0.007

    Aim To report long-term oncological outcomes and organ preservation rate with a chemoradiotherapy-consolidation chemotherapy (CRT-CNCT) treatment for locally advanced rectal cancer (LARC). Method Retrospective analysis of prospectively maintained database was performed. Oncological outcomes of mid-low LARC patients (n=60) were analyzed after a follow-up of 63 (50-83) months. Patients with clinical complete response (cCR) were treated with the watch-and-wait (WW) protocol. Patients who could not achieve cCR were treated with total mesorectal excision (TME) or local excision (LE). Results Thirty-nine (65\%) patients who achieved cCR were treated with the WW protocol. TME was performed in 15 (25\%) patients and LE was performed in 6 (10\%) patients. During the follow-up period, 10 (25.6\%) patients in the WW group had regrowth (RG) and 3 (7.7\%) had distant metastasis (DM). Five-year overall survival (OS) and disease-free survival (DFS) were 90.1\% and 71.6\%, respectively, in the WW group. Five-year OS and DFS were 94.9\% (95\% CI: 88-100\%) and 80\% (95\% CI: 55.2-100\%), respectively, in the RG group. For all patients (n=60), 5-year TME-free DFS was 57.3\% (95\% CI: 44.3-70.2\%) and organ preservation-adapted DFS was 77.5\% (95\% CI: 66.4-88.4\%). For the WW group (n=39), 5-year TME-free DFS was 77.5\% (95\% CI: 63.2-91.8\%) and organ preservation-adapted DFS was 85.0\% (95\% CI: 72.3-97.8\%). Conclusion CRT-CNCT provides cCR as high as 2/3 of LARC patients. Regrowths, developed during follow-up, can be successfully salvaged without causing oncological disadvantage if strict surveillance is performed.

    Metastasis-Induced Acute Pancreatitis Successfully Treated with Chemotherapy and Radiotherapy in a Patient with Small Cell Lung Cancer
    (HINDAWI LTD, 2015-01-01) Okutur, Kerem; Bozkurt, Mustafa; Korkmaz, Taner; Karaaslan, Ercan; Guner, Levent; Goksel, Suha; Demir, Gokhan
    Although involvement of pancreas is a common finding in small cell lung cancer (SCLC), metastasis-induced acute pancreatitis (MIAP) is very rare. A 50-year-old female with SCLC who had limited disease and achieved full response after treatment presented with acute pancreatitis during her follow-up. The radiologic studies revealed a small area causing obliteration of the pancreatic duct without mass in the pancreatic neck, and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) confirmed the metastasis of SCLC. The patient was treated successfully with systemic chemotherapy and radiotherapy delivered to pancreatic field. In SCLC, cases of MIAP can be encountered with conventional computed tomography with no mass image, and positron emission tomography and EUS-FNA can be useful for diagnosis of such cases. Aggressive systemic and local treatment can prolong survival, especially in patients with good performance status.

    The geographical location and differences in tumor biology significantly change the management of gastric cancer. The prevalence of gastric cancer ranks fifth and sixth among men and women, respectively, in Turkey. The international guidelines from the Eastern and Western countries fail to manage a considerable amount of inconclusive issues in the management of gastric cancer. The uncertainties lead to significant heterogeneities in clinical practice, lack of homogeneous data collection, and subsequently, diverse outcomes. The physicians who are professionally involved in the management of gastric cancer at two institutions in Istanbul, Turkey, organized a consensus meeting to address current problems and plan feasible, logical, measurable, and collective solutions in their clinical practice for this challenging disease. The evidence-based data and current guidelines were reviewed. The gray zones in the management of gastric cancer were determined in the first session of this consensus meeting. The second session was constructed to discuss, vote, and ratify the ultimate decisions. The identification of the T stage, the esophagogastric area, imaging algorithm for proper staging and follow-up, timing and patient selection for neoadjuvant treatment, and management of advanced and metastatic disease have been accepted as the major issues in the management of gastric cancer. The recommendations are presented with the percentage of supporting votes in the results section with related data.
