Optimizing the Personalized Care for the Management of Rectal Cancer: A Consensus Statement.

Colorectal cancer is the third most common cancer in Turkey. The current guidelines do not provide sufficient information to cover all aspects of the management of rectal cancer. Although treatment has been standardized in terms of the basic principles of neoadjuvant, surgical, and adjuvant therapy, uncertainties in the management of rectal cancer may lead to significant differences in clinical practice.

Capecitabine-cisplatin versus 5-fluorouracil/leucovorin in combination with radiotherapy for adjuvant therapy of lymph node positive locally advanced gastric cancer.

Aim Of The Study: Although surgery is considered to be curative treatment, recurrence rates are high in gastric cancer. Adjuvant 5-fluorouracil (5-FU) based chemoradiotherapy has been shown to improve the prognosis. We compared tolerability and efficacy of the two different chemotherapy regimens; 5-FU/leucovorin (LV) versus cisplatin with capecitabine (XP) combined with radiotherapy (RT) in the adjuvant therapy of the lymph node positive locally advanced gastric cancer.

Prognostic Factors for Operated Gallbladder Cancer.

Purpose: The prognosis of gallbladder cancer is poor. Lymph node metastasis and the stage are known to be the strongest prognostic factors for survival. The aim of this study was to determine the importance of complementary surgery and other prognostic factors for survival of operated gallbladder cancer.

Gastric Adenocarcinoma Biomarker Expression Profiles and their Prognostic Value.

Expression levels of several molecules implicated in carcinogenesis were examined by immunohistochemical staining, and the prognostic significance of their expression levels in gastric adenocarcinoma (GA) was evaluated. A total of 115 GA and 20 control gastric tissue samples were evaluated by immunohistochemistry using 33 antibodies targeting molecules known to play a part in the development of various tumors. Overexpression of carbonic anhydrase IX (CAIX) and loss of AT-rich interactive domain-containing protein 1A (ARID1A), aldehyde dehydrogenase 1 (ALDH1), and CD44 expression in GA patients were significantly correlated with lymph node (LN) metastasis, advanced tumor stage, and poor prognosis.

Prognostic markers for metastatic colon cancer patients undergoing multiple metastasectomies.

Background/aims: Following metastasis resection, 5-year survival rate has been reported as approximately 40%. There is no consensus regarding prognostic factors related to progression-free survival after repeated metastasectomies.

Materials And Methods: A total of 21 patients with metastatic colorectal cancer who underwent repeated metastasectomies were retrospectively analyzed.

Clinical importance of discordance of hormone receptors and Her2/neu status after neoadjuvant chemotherapy in breast cancer.

Purpose: The aim of this study was to compare the hormone receptors' (HR) and HER2/neu status between core needle biopsy (CNB) and residual tumor after surgery of breast cancer treated with neoadjuvant chemotherapy (NAC), and also to evaluate the impact of discordance and other clinicopathological factors on survival.

Methods: Oestrogen receptor (ER), progesterone receptor (PR) and HER2/neu status were evaluated by immunohistochemistry (IHC) on 90 CNBs of primary tumors and surgical specimens after NAC (study group); 53 patients without NAC served as control group, and discordance was compared between the two groups. The association between discordance of HR status after NAC and various other clinicopathological factors was tested with Spearman's test.

Factors that Affect Patients' Decision-Making about Mastectomy or Breast Conserving Surgery, and the Psychological Effect of this Choice on Breast Cancer Patients.

BACKGROUND: Breast cancer is the most common cancer in women. Primary treatment is surgery, with breast conserving surgery (BCS) being widely used for early-stage disease. Due to changes in body image, depressive symptoms can occur after surgery.
