To determine the risk factors for peritoneal recurrence in gastric cancer patients after curative resection, we included 320 patients with stage I-III primary gastric cancer between January 2008 and June 2012. Data on each patient's surgical and pathological information, preoperative and postoperative tumor markers were collected and analyzed retrospectively. The risk factors for peritoneal recurrence were investigated by univariate and multivariate analysis. In patients with peritoneal recurrence, advanced T or N stage, low differentiation, vascular/lymphatic invasion, perineural invasion, and elevated postoperative CEA/CA19-9 were more common than in patients without peritoneal recurrence...

Adenoid cystic carcinoma is a rare, slow-growing neoplasm. It is most commonly located in the salivary glands, affects people older than 55 years of age, and has a predilection for women. These lesions may recur locally but have shown low metastatic potential. We present the unique case of a 71-year-old female with a nonraised hyperpigmented lesion isolated to the right heel. Confusion surrounded the clinical presentation of this dermatologic lesion, and many physicians postulated several differential diagnoses...

INTRODUCTION: Locoregional recurrence plays a key role in treatment failure of patients with squamous cell carcinoma of the tongue. In a large amount of studies lymph node ratio could be demonstrated as a promising parameter to stratify risk of patients with oral cavity cancer. However data on the influence of lymph node ratio on locoregional recurrence of tongue squamous cell carcinoma is very rare. MATERIAL AND METHODS: Retrospective chart review of 130 patients with treatment naive squamous cell carcinoma of the tongue...

Perineural invasion (PNI) is widely studied in malignant tumors, and its prognostic significance is well demonstrated in the head and neck and prostate carcinomas, but its significance in rectal cancer is controversial. Most studies have focused on evaluating mural PNI (mPNI); however, extramural PNI (ePNI) may influence the prognosis after rectal cancer resection. We evaluated the prognostic value of ePNI compared with mPNI and with non-PNI, in rectal resections after preoperative chemoradiotherapy in 148 patients with pT3 and pT4 rectal carcinomas...

The use of postoperative radiotherapy (PORT) in early stage oral cancer with adverse pathologic features (APFs) is controversial. Prognostically relevant APFs reviewed were perineural invasion, lymphovascular invasion, depth of invasion, worst pattern of invasion, and margin status. The current literature remains divided with regard to the benefit of treatment escalation in these patients; although these patients are at high risk for recurrence, the morbidity of PORT needs to be balanced against the likely benefit in disease control...

BACKGROUND: The purpose of this study was to compare the diagnostic accuracy of positron emission tomography (PET)/MRI with PET/CT for local resectability of head and neck cancer. METHODS: Sequential contrast-enhanced PET/CT-MRI was performed in 58 patients referred for the staging or restaging of head and neck cancer. Tumors were assessed with PET/CT and PET/MRI for the presence of resectability-defining factors: T4b status (mediastinal invasion, invasion of the prevertebral space, and vascular encasement), and another 8 findings that would imply obstacles for surgical cure (invasion of the laryngeal cartilage, invasion of the preepiglottic fat pad, perineural spread, orbital invasion, bone infiltration, skull base invasion, dural infiltration, and invasion of the brachial plexus)...

Xanthogranulomatous pyelonephritis (XGPN) is an atypical long-term pyelonephritis with destruction of renal parenchyma and a long-term inflammatory infiltrate of macrophages. Reported presentations of transitional cell carcinoma (TCC) are different. A 73-year-old woman presented with loin pain, prostration, and fever. Computed tomography scan revealed poor cortical enhancement of the kidney, but some of the images bore resemblance to the characteristic "bear's paw" sign, consistent with XGPN with a 7-cm perinephric collection...

Purpose: Large diameter perineural prostate cancer is associated with poor outcomes. GDNF, with its co-receptor GFRα1, binds RET and activates downstream pro-oncogenic signaling. Since both GDNF and GFRα1 are secreted by nerves, we examined the role of RET signaling in prostate cancer. <p>Experimental Design: Expression of RET, GDNF and/or GFRα1 was assessed. The impact of RET signaling on proliferation, invasion and soft agar colony formation, perineural invasion and growth in vivo was determined...

Background: The presence of lymph nodes metastasis is one of the most important prognostic indicators in gastric cancer. The micrometastases have been studied as prognostic factor in gastric cancer, which are related to decrease overall survival and increased risk of recurrence. However, their identification is limited by conventional methodology, since they can be overlooked after routine staining. Aim: To investigate the presence of occult tumor cells using cytokeratin (CK) AE1/AE3 immunostaining in gastric cancer patients histologically lymph node negative (pN0) by H&E...

INTRODUCTION: Gastric carcinoma is a leading cause of death worldwide with a five year survival of 10-15% even after curative resection. Trastuzumab has emerged as a potential targeted therapy in treatment of Her 2 positive gastric cancer. Her2 positivity ranges from 7-34% in studies across the world. There is a paucity of Indian studies hence a need for determination of Her2 expression in Indian population for better patient management. This study was carried out to determine the frequency of Her 2 expression in gastric carcinoma by immunohistochemistry (IHC) technique and to evaluate its association with histopathological parameters...

Perineural invasion (PNI) has been implicated as a poor prognostic indicator in many cancers. The National Comprehensive Cancer Network recommends consideration of observation or adjuvant therapy in the presence of PNI in early colon cancer. These recommendations are based on single institutional studies that fail to evaluate PNI within the context of adjuvant chemotherapy. The US National Cancer Database (2004-2012) was reviewed for patients with node negative colon cancer, and stratified by PNI and receipt of chemotherapy...

Cutaneous adenoid cystic carcinoma (CACC) is an extremely rare neoplasm of head and neck region, and is characterized by propensity for local recurrence and perineural invasion. Late distant metastases occur usually to lungs. Although patients with lung metastases from CACC cannot be cured, long-term survival may be possible due to its slow-growing malignancy. We report a case of a 69-year-old female with lung metastases from CACC 23 years after initial surgery of scalp nodule.

Although Wilms tumor 1 (WT1)-associated protein (WTAP) was initially found to be a specific WT1-binding protein, it has increasingly attracted attention because of its oncogenic role in various types of malignancies, including cholangiocarcinoma, glioblastoma and acute myeloid leukemia. However, the clinical impact of WTAP on pancreatic ductal adenocarcinoma (PDAC) is still unknown. A total of 145 patients who underwent surgical treatment from 2004 to 2008 were enrolled in the present study. The cytoplasmic and nuclear expression of WTAP in tumor and adjacent normal tissues was examined by immunohistochemical analysis in order to investigate the relationship between WTAP and the clinicopathological factors and prognosis of patients with PDAC...
