Prediction of Pathologic Tumor Response to Chemoradiation Therapy in Locally Advanced Esophageal Cancer Using a Jacobian Map

Preoperative therapy in locally advanced esophageal cancer

Esophageal cancer is an aggressive malignancy associated with dismal treatment outcomes. Presence of two distinct histopathological types distinguishes it from other gastrointestinal tract malignancies. Surgery is the cornerstone of treatment in locally advanced esophageal cancer (T2 or greater or node positive); however, a high rate of disease recurrence (systemic and loco-regional) and poor s...

Tumor volume as outcome determinant in patients treated with chemoradiation for locally advanced esophageal cancer.

OBJECTIVE The currently used tumor-node metastasis (TNM) staging method is generally not applicable to patients with unresectable esophageal carcinomas. There is a need for both an efficient, easy-to-perform clinical classification and for identification of pretherapeutic prognostic factors that would be useful for oncologists, one of which is tumor volume. METHODS Records of 148 patients, ad...

Comparison of 5FU-base Chemoradiation with and without Eloxatin on Pathologic Complete Response in Neoadjuvant Chemoradiation of Rectal cancer

  Background and Objectives: To compare pathologic complete response (pCR) in patients with advanced rectal cancer receiving neoadjuvant chemoradiotherapy (NACT) by 5-FU or Xeloda (capecitabine) with and without Eloxatin (oxaloplatin injection). Materials and Methods: Seventy-five consecutive patients with the diagnosis of advanced rectal adenocarcinoma were included. Two basic chemotherapy r...

Endoscopic Criteria for Evaluating Tumor Stage after Preoperative Chemoradiation Therapy in Locally Advanced Rectal Cancer

PURPOSE Local excision may be an another option for selected patients with markedly down-staged rectal cancer after preoperative chemoradiation therapy (CRT), and proper evaluation of post-CRT tumor stage (ypT) is essential prior to local excision of these tumors. This study was designed to determine the correlations between endoscopic findings and ypT of rectal cancer. MATERIALS AND METHODS ...
