Hypopharyngeal cancer and esophageal cancer often occur synchronously or metachronously. Timely screening, diagnosis and individual treatment are important to improve the prognosis of patients. At present, there is no clinical guideline or consensus in this cross-cutting area in China, and there is a need of consistent diagnosis and treatment recommendation for these patients. Under the sponsorship of the Committee of Esophageal Cancer in China Anti-Cancer Association, the Chinese Working Group on Cooperative Diagnosis and Treatment of Hypopharyngeal and Esophageal Cancer was established by domestic experts in the fields of otolaryngology head and neck surgery, radiation oncology, and gastrointestinal endoscopy. This consensus document on multiple primary cancers (simultaneous or metachronous) of the hypopharynx and esophagus was developed through literature review, collective experience and expert discussions. The goals of the consensus include: (1) raising concern for this cross-cutting field; (2) establishing a preliminary clinical diagnosis and treatment recommendation; (3) preparing for the establishment of future high-level guidelines through standardized clinical practice.

Collision tumor is a synchronous neoplasm wherein two histologically distinct tumors co-exist within the same anastomosis site. Collision tumor can occur in any organ, but the incidence is markedly rare. Additionally, preoperative diagnosis can be challenging to the radiologist. Herein, we report an age 60 male with collision tumor of rectal adenocarcinoma and diffuse large B-cell lymphoma, presented as a semi-annular wall thickening and bulky exophytic mass on MR imaging.

PURPOSE: Pancreatic cancer associated double primary tumors are rare and their clinicopathologic characteristics are not well elucidated. MATERIALS AND METHODS: Clinicopathologic factors of 1,352 primary pancreatic cancers with or without associated double primary tumors were evaluated. RESULTS: Of resected primary pancreatic cancers, 113 (8.4%) had associated double primary tumors, including 26 stomach, 25 colorectal, 18 lung, and 13 thyroid cancers. The median interval between the diagnoses of pancreatic cancer and associated double primary tumors was 0.5 months. Overall survival (OS) of pancreatic cancer patients with associated double primary tumors was longer than those with pancreatic cancer only (median, 23.1 months vs. 17.0 months; p=0.002). Patients whose pancreatic cancers were resected before the diagnosis of metachronous tumors had a better OS than patients whose pancreatic cancer resected after the diagnosis of metachronous tumors (48.9 months and 13.5 months, p=0.001) or those whose pancreatic cancers were resected synchronously with non-pancreas tumors (19.1 months, p=0.043). The OS of pancreatic cancer patients with stomach (33.9 months, p=0.032) and thyroid (117.8 months, p=0.049) cancers was significantly better than those with pancreas cancer only (17.0 months). CONCLUSION: About 8% of resected pancreatic cancers had associated double primary tumors, and those from the colorectum, stomach, lung, and thyroid were common. Patients whose pancreatic cancer was resected before the diagnosis of metachronous tumors had better OS than those resected after the diagnosis of metachronous tumors or those resected synchronously.

BACKGROUND: Simultaneity multiple primary lung cancer always is a rare disease, but in recent years due to the progress of the diagnosis and treatment means detection rate increased. This study summarized the clinical data of 31 cases of synchronous multiple primary lung cancer (sMPLC) analysis, further to explore the diagnosis, treatment and prognosis of MPLC. METHODS: Sum up the clinical data of 31 cases of simultaneous multiple primary lung cancer, the diagnostic method, surgical methods, pathology, were retrospectively analyzed. RESULTS: All the patients are thoracoscope surgery, no deaths. Thin high resolution computed tomography (CT) in preoperative found multiple lung nodules. Lesions located in the same side of the same period surgical treatment, the operation method is given priority to with under the thoracoscope lung + the lobectomy; Lesions located in bilateral, all staged operation, the time interval for 3 months-4 months. CONCLUSIONS Thin layer distinguish CT preoperative diagnosis is the best way to simultaneous multiple primary lung cancer. Multiple primary lung cancer incidence of ipsilateral lung at the same time higher than that of bilateral lung (23:8), type, around 94%, the most common histology to adenocarcinoma, 80.6% (25/31). Primary lesions under thoracoscope lobectomy plus the lobectomy of secondary lesions is the most commonly used.

BACKGROUND/AIMS: Esophageal squamous cell carcinoma (ESCC) and colorectal neoplasms (CRNs) share risk factors. We aimed to investigate whether the CRN risk is increased in ESCC patients. METHODS: ESCC patients who underwent a colonoscopy within 1 year of diagnosis were retrospectively analyzed. Patients were matched 1:3 by age, gender, and body mass index to asymptomatic controls. CRN was defined as the histological confirmation of adenoma or adenocarcinoma. Advanced CRN was defined as any of the following: > or =3 adenomas, high-grade dysplasia, villous features, tumor > or =1 cm, or adenocarcinoma. The risk factors for both CRN and advanced CRN were evaluated by univariate and multivariate analyses. RESULTS: Sixty ESCC patients were compared with 180 controls. The ESCC group had significantly higher numbers of CRNs (odds ratio [OR], 2.311; 95% confidence interval [CI], 1.265 to 4.220; p=0.006) and advanced CRNs (OR, 2.317; 95% CI, 1.185 to 4.530; p=0.013). Significant risk factors for both CRN and advanced CRN by multivariate analysis included ESCC (OR, 2.157, 95% CI, 1.106 to 4.070, p=0.024; and OR, 2.157, 95% CI, 1.045 to 4.454, p=0.038, respectively) and older age (OR, 1.068, 95% CI, 1.032 to 1.106, p<0.001; and OR, 1.065, 95% CI, 1.024 to 1.109, p=0.002, respectively). CONCLUSIONS: The rates of CRN and advanced CRN are significantly increased in ESCC. Colonos-copy should be considered at ESCC diagnosis.

OBJECTIVETo analyze the imaging characteristics of hepatic epithelioid hemangioendothelioma (EHE) and their correlation with histopathological findings.

METHODSCT and MRI imaging and histopathological characteristics of five patients with hepatic EHE were retrospectively reviewed and the correlation of their imaging characteristics with pathological findings was analyzed.

RESULTSA total of 92 lesions were found in the 5 patients, all presenting with multiple nodules. All the 92 lesions were located within a 2-cm zone heneath the hepatic capsule, i.e., the shortest distance from the horder of lesions to the hepatic capsule. 28 of the 92 lesions showed the "capsular retraction" sign. 36 lesions were found in three patients receiving MRI. 77.8% of the 36 lesions demonstrated the "halo" sign on a fat-suppression T2- weighted image, while 91.7% after contrast enhancement. A peripheral dark rim was found in 91.7% of the lesions on a fat-suppression T2-weighted image. In addition, 36.1% of the lesions showed slight internal or edge enhancement at the hepatohiliary phase. In the two patients receiving CT examination, 7 of 56 lesions demonstrated the "halo" sign.

CONCLUSIONSHepatic EHE may manifest as nodular lesions with predilection of peripheral subcapsular growth and nodular confluence, together with "halo" sign and " capsular retraction". The peripheral dark rim on a fat-suppression T2-weighted image and slight enhancement at the hepatobiliary phase can help to improve the accuracy of diagnosis and differential diagnosis of this hepatic tumor. MRI is superior to CT imaging to denict their intra-lesional characteristics.
