BACKGROUND: A modest proportion of patients with early stage hormone receptor-positive (HR+), HER2-negative (HER2-) breast cancer benefit from adjuvant chemotherapy. Traditionally, treatment recommendations are based on clinical/pathologic criteria that are not predictive of chemotherapy benefit. Multigene assays provide prognostic and predictive information that can help to make more informed treatment decisions. The MAGIC survey evaluated international differences in treatment recommendations, how traditional parameters are used for making treatment choices, and for which patients treating physicians feel most uncertain about their decisions...

Extraskeletal osteosarcoma is a rare and invasive malignancy, typically located in the soft tissue without attachment to the skeleton. The present study reports a case of a primary mesenteric extraskeletal osteosarcoma of a 71-year-old woman. The patient complained of an incomplete defecation. Colonoscopy showed an ulcer with impression of external compression of the sigmoid. An additional abdominal computed tomography (CT) scan revealed a large, almost completely calcified, mass in the left lower abdomen causing hydronephrosis of the left kidney...

BACKGROUND: Current treatment guidelines for limited-stage small-cell lung cancer (SCLC) recommend concomitant platinum-based chemo-radiotherapy plus prophylactic cranial irradiation, based on the premise that SCLC disseminates early, and is chemosensitive. However, although there is usually a favourable initial response, relapse is common and the cure rate for limited-stage SCLC remains relatively poor. Some recent clinical practice guidelines have recommended surgery for stage 1 (limited) SCLC followed by adjuvant chemotherapy, but this recommendation is largely based on the findings of observational studies...

Oesophageal cancer is a relatively uncommon malignancy, but with poor prognosis. Despite several treatment options that are available, the 5-year survival rates rarely exceed 40%. This review discusses the main challenges of oesophageal cancer, the available treatment options, and the most effective treatment in terms of overall survival. The outcomes of clinical trials show that neo-adjuvant chemo-radiotherapy using cisplatin and 5-fluorouracil followed by oesophagectomy results in the greatest survival. However, the optimal chemotherapy and radiotherapy schedule remains unclear...

AIMS: The clinical outcome of patients with locally advanced rectal cancer submitted to neo-adjuvant chemo-radiotherapy (CRT) is influenced by tumour response to treatment, which is reflected by tumour regression grade (TRG) and post-treatment (y) TNM stage. Little is known on the prognostic value of pre-treatment histopathological features of the tumour which may be useful to discriminate potential non-responders and to design tailored therapeutic strategies. In this study, we aimed to investigate the prognostic role of poorly differentiated clusters (PDC) of neoplastic cells in pre-treatment biopsies of rectal cancer submitted to neo-adjuvant CRT...

Purpose. Radical surgical resection with adjuvant chemotherapy or chemo-radiotherapy is the most effective treatment for pancreatic ductal adenocarcinoma (PDAC). However, relatively few studies investigate the prognostic significance of biological markers in PDAC. This study aims to look into the expressions of vimentin, Ki67, and CD44 in PDAC surgical specimens and their potential prognostic implications in survival. Method. The study was designed as retrospective, and vimentin, Ki67, and CD44 expressions were evaluated by immunohistochemistry in 53 pancreatic ductal adenocarcinoma cases...

D-penicillamine (DPEN), a copper chelator, has been used in the treatment of Wilson's disease, cystinuria, and rheumatoid arthritis. Recent evidence suggests that DPEN in combination with biologically relevant copper (Cu) concentrations generates H2O2 in cancer cell cultures, but the effects of this on cancer cell responses to ionizing radiation and chemotherapy are unknown. Increased steady-state levels of H2O2 were detected in MB231 breast and H1299 lung cancer cells following treatment with DPEN (100µM) and copper sulfate (15µM)...

OBJECTIVE: The aim of our study was to try to validate 3 promising predictive biomarkers in a database based on prospective trials comparing bacillus Calmette-Guerin (BCG) with mitomycin-C and a combination of epirubicin and interferon, respectively. BACKGROUND: The most common form of bladder cancer is non-muscle-invasive tumors treated initially with transurethral resection. Unfortunately more than half recur and some also progress. Consequently, an attempt to prevent poor outcome is frequently made by intravesical instillations either by chemo- or immunotherapy...

Both endocrine and chemotherapy can be utilized for breast cancer patients' management, in multiple setting (i.e., primary systemic therapy, adjuvant, metastatic treatment). Health-related quality of life in breast cancer survivors can be significantly influenced by cognitive impairment, which has been related in several previously reported experiences to systemic therapies administration. However, although the growing body of literature, the impact of both chemo- and endocrine therapy on cognitive function is currently unclear, due to many confounding factors (i...

BACKGROUND: Although in clinical practice adjuvant chemotherapy (CT) and endocrine therapy (ET) are administered sequentially in patients with hormone-receptor positive breast cancer, the optimal timing, i.e. concurrent or sequential administration, of these treatments has been scarcely investigated. To better clarify this issue we conducted a systematic review and meta-analysis of randomized studies comparing these two modalities of administrations in terms of disease-free survival (DFS) and overall survival (OS)...

Lung cancer is the foremost cause of cancer-related deaths world-wide. Both, the major forms of lung cancer, Non-small cell lung cancer (NSCLC) and Small cell lung cancers (SCLC), have responded effectively to chemo-, radiation and adjuvant-therapies. Tumor removal through surgery also appeared as a good therapeutic strategy. However, these therapies demonstrated unfavourable side-effects, and hence novel drugs targeting lung cancer emerged essential. Activation of epidermal growth factor receptor (EGFR)-tyrosine kinases is a key reason for lung cancer progression...

BACKGROUND: Stathmin1 (STMN1) is a cytosolic phosphoprotein that regulates cellular microtubule dynamics and is known to have oncogenic activity. Despite several reports, its roles in gastric cancer (GC) remain unclear owing to a lack of analyses of highly metastatic cases. This study aimed to investigate STMN1 as a prognostic and predictive indicator of response to paclitaxel therapy in patients with GC, including inoperable cases. METHODS: Immunohistochemical analysis of STMN1 was performed on both operable (n=95) and inoperable GC (n=61) samples...

Pancreatic cancer management remains a major challenge to society. Poor prognosis results in dismal survival rates and quality of life for pancreatic cancer patients post chemo/radiation therapies. Although progress has been made in drug development for chemotherapeutics targeting pancreatic cancer, accompanying issues of resistance to these drugs renders the treatment futile. Emerging area of cancer chemoprevention is gaining importance with natural/dietary compounds serving as novel agents with strong anticancer properties; these are pleiotropic agents targeting multiple pathways with minimal toxicities in the surrounding normal tissue...

Malignant peripheral nerve sheath tumor (MPNST) of oral cavity is an extremely uncommon malignancy. Less than 15 cases have been reported since 1973 though none of them describes a distant metastasis. We present a rare case of MPNST of the tongue who presented with features of hypoglossal nerve palsy. Incisional biopsy showed a malignant spindle cell tumor in the sub-epithelial connective tissue. The tumor cells were immune-positive for S-100. He underwent surgery followed by adjuvant chemo-radiation. Later the disease recurred in the form of isolated pelvic bone metastasis...
