A key question in precision medicine is how functional heterogeneity in solid tumors informs therapeutic sensitivity. We demonstrate that spatial characteristics of oncogenic signaling and therapy response can be modeled in precision-cut slices from Kras-driven non-small cell lung cancer (NSCLC) of varying histopathologies. Unexpectedly, profiling of in situ tumors demonstrates that signaling stratifies mostly according to histopathology, showing enhanced AKT and SRC activity in adenosquamous carcinoma (ASC), and MAPK activity in adenocarcinoma (AC)...

The aim of the present study was to elucidate the characteristics and outcomes of abdominal esophageal cancer patients who were treated with esophagectomy. The records of 210 esophagectomy patients were retrospectively reviewed and the differences in postoperative outcomes and disease-specific survival between squamous cell carcinoma and adenocarcinoma were evaluated. Of the 20 abdominal esophageal cancer patients, 11 had squamous cell carcinoma, 8 had adenocarcinoma and 1 had adenosquamous cell carcinoma. The body mass index and serum albumin levels were significantly lower in the squamous cell carcinoma patients compared with those in the adenocarcinoma patients, and abdominal lymph node metastasis was significantly more frequent in the adenocarcinoma patients...

A retrospective population-based observational study using cancer registration data of women diagnosed with invasive cervical cancer between 2006 and 2010, in England, was carried out to explore how different morphological subtypes affect survival rates. Age-standardised net survival rates by morphological subtype are presented alongside with excess mortality modelling accounting for the impact of demographic, diagnostic and tumour factors. The three main morphological subtypes (squamous cell carcinoma (SCC), adenocarcinoma and adenosquamous carcinoma) have similar one-year net survival rates of approximately 85%...

Background: FOLFIRINOX (FX) has been reported as an effective treatment for unresectable advanced pancreatic cancer. However, FX is associated with a high incidence of adverse events (AEs). A previous phase II study in Japan showed high incidences of hematological AEs, including febrile neutropenia (22.2%). A modified FX regimen (mFX) may decrease the rates of AEs and be more effective than FX by improving the treatment compliance. Aims: To assess the safety and efficacy of first-line mFX for unresectable advanced pancreatic cancer...

A 51-year-old white female presented with a painful ulcer of the left ventrolateral tongue. An incisional biopsy confirmed a diagnosis of adenosquamous carcinoma. The adenosquamous carcinoma is an uncommon malignant tumor with histopathological features of a squamous carcinoma and an adenocarcinoma. A definitive diagnosis requires histopathological examination of a deep biopsy involving the submucosal tissue. This malignant tumor shows aggressive behavior with early invasive growth and a poor prognosis. The histopathological findings and differential diagnosis of a case of adenosquamous carcinoma of the tongue are discussed...

Adenosquamous carcinoma of the pancreas (ASCP) is an uncommon variant of exocrine pancreatic malignancies, characterized by a histological admixture of adenomatous and squamous cell elements. This cancer is characterized by a poorly differentiated histology and a poorer clinical outcome compared to pancreatic ductal adenocarcinoma (PDAC). Unlike PDAC, that is characterized by a low microvascular density (MVD) and collapsed vasculature, no data are available about angiogenesis in ASPC. Immunohistochemical evaluation of MVD and trypatse-positive mast cells (MCs) were performed on a single case of ASCP compared to PDAC...

There are a few entities that account for most solid and cystic masses of the pancreas. The pancreas harbors a wide array of diseases, including adenocarcinoma, and its variants, such as anaplastic and adenosquamous carcinoma. Other neoplasms include acinar cell carcinoma, solid pseudopapillary tumor, and sarcomas. Benign lesions include hamartomas, hemangiomas, lymphangioma, and plasmacytoma. Isolated metastases include renal cell carcinoma, melanoma, and other carcinomas. Benign inflammatory conditions, such as autoimmune pancreatitis and groove pancreatitis can also mimic solid neoplasms of the pancreas...

BACKGROUND: Based primarily on studies concerning early-stage tumours (treated surgically), and locally advanced disease (treated with chemoradiation), the prognosis for women with adenocarcinoma (AC) or adenosquamous (AS) carcinoma has been reported to be poorer than those with squamous cell carcinoma (SCCA) of the cervix. It is unclear whether differences in prognosis also persist in the setting of recurrent or metastatic disease treated using chemotherapy doublets with or without bevacizumab...
