BACKGROUND: Neoadjuvant chemotherapy followed by surgery is the standard of care for UK patients with locally advanced resectable oesophageal carcinoma (OeC). However, not all patients benefit from multimodal treatment and there is a clinical need for biomarkers which can identify chemotherapy responders. This study investigated whether the proportion of tumour cells per tumour area (PoT) measured in the pre-treatment biopsy predicts chemotherapy benefit for OeC patients. PATIENTS AND METHODS: PoT was quantified using digitized haematoxylin/eosin stained pre-treatment biopsy slides from 281 OeC patients from the UK MRC OE02 trial (141 treated by surgery alone (S); 140 treated by 5-fluorouracil/cisplatin followed by surgery (CS))...

BACKGROUND: Although most triple-negative breast cancer (TNBC) patients initially respond to chemotherapy, residual tumor cells frequently persist and drive recurrent tumor growth. Previous studies from our laboratory and others' indicate that TNBC is heterogeneous, being composed of chemo-sensitive and chemo-resistant tumor cell subpopulations. In the current work, we studied the invasive behaviors of chemo-resistant TNBC, and sought to identify markers of invasion in chemo-residual TNBC...

BACKGROUND: Micrometastasis (MM) in colorectal cancer (CRC) is not considered in tumour-node-metastasis (TNM) staging currently and also the prognostic significance of these occult tumoural cells is not proven yet. This study was designed to find whether MM to bone marrow (BM) and/or liver cause upstaging of the tumour according to conventional staging system and if it may alter the survival rate. METHODS: Thirty-eight CRC patients who were candidates of surgical procedure were enrolled in our cross-sectional study...

The World Health Organization (WHO) classification from 2014 differentiates between different subtypes of mucinous adenocarcinoma of the uterine cervix. A gastric subtype was recently described that showed no association with high-risk human papillomavirus (HPV) infections, has a poor prognosis, is mainly diagnosed in women of Asian origin and can occur in patients with Peutz-Jeghers syndrome. Although no clear grading system has been recommended in the WHO classification, it is likely that grading of adenocarcinomas of the uterine cervix will partly be based on the different patterns of invasion...

BACKGROUND: Neoadjuvant chemoradiation therapy (CRT) increases pathological complete response (pCR) rates compared to radiotherapy alone in patients with stage II-III rectal cancer. Limited evidence addresses whether radiotherapy dose escalation further improves pCR rates. Our purpose is to measure the effects of radiotherapy dose and other factors on post-therapy pathologic tumor (ypT) and nodal stage in rectal cancer patients treated with neoadjuvant CRT followed by mesorectal excision...

INTRODUCTION: Nasopharyngeal carcinoma among the children has been rare accounting for only 1% of all pediatric malignancies. Both genetic and environmental factors have contributed to the development of nasopharyngeal carcinoma. Among the children there was a higher rate of undifferentiated histology. The mean age of nasopharyngeal carcinoma diagnosis has been 11 years old age; and the most common site was nasopharynx. Palpable lymphadenopathy, dysphasia and neural defect were common associated signs...

A 63-year-old man with dysphagia was referred to our hospital. He was found to have a type 2 tumor extending from the lower thoracic esophagus to the esophagogastric junction via upper gastrointestinal endoscopy. A biopsy revealed adenocarcinoma with overexpression of the human epidermal growth factor type 2(HER2). The tumor was type I according to Siewert's classification, as the epicenter of the tumor was 27mm to the oral side from the esophago-gastric junction. The clinical diagnosis was T3N1M1, stage IV according to the Japanese Classification of Gastric Carcinoma, and T3N2M0, stage III per the Japanese Classification of Esophageal Cancer...

A 68-year-old woman who presented with a left axillary mass was admitted. A computed tomography scan showed swelling ofthe left axillary and supraclavicular lymph nodes, but magnetic resonance imaging(MRI)and fluorodeoxyglucose positron emission tomography(FDG-PET)did not reveal these primary sites. Histological findings of the axillary mass revealed a HER2-positive adenocarcinoma. We diagnosed the patient with axillary nodal metastasis ofadenocarcinoma ofan unknown primary site and treated her with neoadjuvant chemotherapy including paclitaxel and trastuzumab followed by doxorubicin and cyclophosphamide...

BACKGROUND: Although surgical resection is the only curative strategy for pancreatic cancer, the prognosis of patients with pancreatic cancer remains poor. Recently, neoadjuvant treatment has been frequently employed as a promising treatment. Here, the mid-term results of neoadjuvant chemoradiotherapy(NACRT)using S-1, which has been performed in our hospital since 2008, are reported. METHODS: Seventy-nine patients with resectable or borderline resectable pancreatic ductal adenocarcinoma, who had been intended to undergo NACRT treatment using S-1, were enrolled...

Postoperative chemotherapy was initially conducted with surgical treatment as part of a multimodal treatment strategy for esophageal squamous cell carcinoma. Subsequently, a randomized trial comparing post- versus pre-operative chemotherapy with cisplatin and 5-fluorouracil demonstrated the superior efficacy of neoadjuvant treatment with FP(CF). However, the results of subgroup analysis based on T factor revealed no efficacy for cT3 tumors. To improve the survival rate in patients with cT3 tumors, treatments with neoadjuvant chemotherapy using FP(CF)plus docetaxel and concurrent FP(CF)plus radiation were conducted to assess the feasibility of preoperative adjuvant treatment and surgery after neoadjuvant treatment...

Adjuvant chemotherapy aims to eradicate residual micro-metastatic tumor cells existing at distant sites outside the surgical field. The current standard adjuvant chemotherapy is S-1 for 1 year or capecitabine plus oxaliplatin for 6 months after D2 gastrectomy. However, there are some rooms in the overall survival of Stage III. Neoadjuvant chemotherapy(NAC)is a promising approach that combines intensive chemotherapy with high compliance; however, it is under development in Japan. Two JCOG phase II trials suggested that NAC was effective for bulky nodal disease...
