OBJECTIVE: The recommended treatment for O6 -methylguanine-DNA methyltransferase (MGMT) promoter unmethylated glioblastoma (GBM) is radiation therapy with concurrent/adjuvant temozolomide (TMZ). However, it is well known that the clinical benefit from TMZ is lower in these patients. We sought to analyze patterns of care and outcomes of chemoradiation versus radiation alone in this cohort using a large, hospital database. PATIENTS AND METHODS: Patients diagnosed with MGMT promoter unmethylated GBM from 2010 to 2012 who received radiation (RT) or chemoradiation (CRT) were identified in the National Cancer Database...

INTRODUCTION: The FIR phase II study (NCT01846416) evaluated the efficacy and safety of anti-programmed death-ligand 1 (PD-L1) atezolizumab in advanced non-small-cell lung cancer (NSCLC) selected by tumor cell (TC) or tumor-infiltrating immune cell (IC) PD-L1 expression. METHODS: Patients with PD-L1 TC2/3 (PD-L1 staining on ≥5% of TC) or IC2/3 tumors (PD-L1 staining on ≥5% of IC; determined by SP142 PD-L1 immunohistochemistry assay) with paired fresh and archival histology samples were recruited into Cohort 1 (chemotherapy-naïve/>6 months between adjuvant chemotherapy and recurrence), Cohort 2 (≥ second-line without brain metastases), or Cohort 3 (≥ second-line with treated brain metastases)...

CONTEXT-: Patients with gastrointestinal cancers are at high risk for functional problems that are generally accompanied by a decline in their overall status and intense psychological distress. OBJECTIVES: This study compares the level of functioning in individuals with gastric cancer (GC) and colorectal cancer (CRC) and analyzes whether improved functioning can be explained by patients' psychological status and coping strategies. METHODS: Prospective, transversal, multicenter study in patients with non-metastatic GC and CRC prior to initiating adjuvant chemotherapy...

Objective: Breast and thyroid cancers are commonly encountered malignancies. Increased risk of breast cancer in follow-up period of thyroid cancer or vice versa has been reported. However, they have some associations, synchronous presentation of these tumors is rare. We presented 12 patients diagnosed as breast and thyroid cancer and treated at the same time. Materials and Methods: Mastectomy and thyroidectomy were performed in 19 patients at the same time. 7 patients were excluded because of benign thyroid pathology...

Glioblastoma (GBM) is one of the most aggressive malignant tumors with an overall dismal survival averaging one year despite multimodality therapeutic interventions including surgery, radiotherapy and concomitant and adjuvant chemotherapy. Few drugs are FDA approved for GBM, and the addition of temozolomide (TMZ) to standard therapy increases the median survival by only 2.5 months. Targeted therapy appeared promising in in vitro monolayer cultures, but disappointed in preclinical and clinical trials, partly due to the poor penetration of drugs through the blood brain barrier (BBB)...

BACKGROUND: The optimal timing of (neo)adjuvant trastuzumab initiation with respect to chemotherapy and surgery remains undefined. METHODS: Retrospective analysis of a large institutional database of HER2-positive patients who received anti-HER2 therapy. We included all Stage I to III patients treated with trastuzumab with a minimum follow up of 3 years. The date of first breast biopsy was recorded as initial diagnosis. RESULTS: A total of 506 patients [adjuvant: 386 (76%)-neo-adjuvant: 120 (24%)] were included...

The number of elderly gastric cancer (GC) patients has been rapidly increasing worldwide, but inadequate understanding regarding elderly GC patients has led to the paucity of appropriate treatment decisions. Our study evaluates clinicopathological characteristics and prognoses of elderly GC patients after R0 resection. Overall, 1877 consecutive GC patients who underwent R0 gastrectomy at four centers were enrolled. We divided patients into three groups according to age: young, middle, and elderly. We then analyzed clinicopathological characteristics and prognoses...

BACKGROUND: Multidisciplinary care is critical for the successful treatment of stage III colorectal cancer, yet receipt of adjuvant chemotherapy remains unacceptably low. Peer support, or exposure to others treated for colorectal cancer, has been proposed as a means to improve patient acceptance of cancer care. OBJECTIVE: The purpose of our study was to evaluate the effect of peer support on the attitudes of patients with colorectal cancer toward chemotherapy and their adherence to it...

OBJECTIVE: To compare short-term and oncologic outcomes of patients with cancer who underwent open pancreaticoduodenectomy (OPD) versus minimally invasive pancreaticoduodenectomy (MIPD) using the National Cancer Database. SUMMARY BACKGROUND DATA: MIPD, including laparoscopic and robotic approaches, has continued to gain acceptance despite prior reports of increased short-term mortality when compared with OPD.

Surgery represents the only chance of cure for patients with gastroesophageal adenocarcinoma; however surgery alone does not cure most patients. Over the past decade, several multimodality adjunctive treatments have improved survival for patients with operable gastroesophageal adenocarcinoma who are undergoing surgical resection; these include peri-operative chemotherapy, neoadjuvant chemoradiotherapy, adjuvant chemotherapy and adjuvant chemoradiotherapy. More recently, the results of several large randomised trials are leading to a shift in the peri-operative treatment of gastroesophageal cancer, away from anthracycline-based and towards taxane-based chemotherapy regimens...

To identify impacts of different combined regimens of stereotactic body radiation therapy (SBRT) and chemotherapy on survival of patients with locally advanced pancreatic cancer (LAPC) and factors correlated with determinations of different combinations. Four hundred and nineteen patients with radiographically and biopsy-proven LAPC were prospectively enrolled. Factors associated with different strategies were analyzed with Chi-square test and contingency coefficients. Cox regression was used to identify factors predictive of survival...

PURPOSE: To determine the associations between lysosomal-associated transmembrane protein 4b (LAPTM4B) gene copy number and response to different chemotherapy regimens in hormone receptor negative (HR-) primary breast carcinomas. PATIENTS AND METHODS: Two cohorts were analyzed: (1) 69 core biopsies from HR-breast carcinomas treated with neoadjuvant chemotherapy (anthracycline based in 72.5% of patients and non-anthracycline based in 27.5% of patients). (2) Tissue microarray (TMA) of 74 HR-breast carcinomas treated with adjuvant therapy (77...

PURPOSE: Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease; however, the frequency of recurrence can be reduced if curative surgery following adjuvant chemotherapy is applied. At present, adjuvant chemotherapy is uniformly performed in all patients, as it is unclear which tumor types are controlled best or worst. We investigated patients with recurrence to establish the optimum treatment strategy. METHODS: Of 138 patients who underwent curative surgery for PDAC, 85 developed recurrence...

This study was designed to investigate the effect of neoadjuvant chemotherapy on the expression of hormone receptors and ki67 in Chinese female breast cancer patients. The expression of estrogen receptor (ER), progesterone receptor (PR) and Ki67 among 525 neoadjuvant chemotherapy cases was studied by immunohistochemistry (IHC). Differences between specimens made through preoperative core needle biopsy (CB) and excised tissue biopsy (EB) were observed. The positive rates of ER, PR and Ki67 in CB and EB were 65...

OBJECTIVE: Locally advanced endometrioid adenocarcinoma (LA-EAC) accounts for the majority of deaths for this cancer, yet there is no consensus on adjuvant treatment after surgery. Past studies suggest that combined modality treatment (CMT) may improve outcomes over treatment with chemotherapy (CT) or radiation therapy (RT, either external beam radiotherapy [EBRT] or vaginal brachytherapy [VBT]) alone. Using a large US-based population-based registry, we evaluated adjuvant CMT in LA-EAC and the relative benefit of regional EBRT compared to focused VBT...

An incomplete regression of the mammary line during embryogenesis occurs in 0.2-6% of the population, which may result in the presence of ectopic breast tissue (EBT). The development of a carcinoma in the EBT is a rare event. The authors present a case report of a 76-year-old female patient, with a lobular carcinoma in an abdominal wall EBT submitted to surgery and adjuvant chemotherapy.
