Primary lung cancer frequently metastasizes to distant organs. The pancreas is a relatively infrequent site of metastasis. Furthermore, obstructive jaundice resulting from pancreatic metastasis is extremely rare. This paper examines the case of a 65-year-old woman with small cell lung cancer initially presenting with extrahepatic biliary obstruction. The patient underwent percutaneous transhepatic biliary drainage. The obstruction was relieved with a stent placement, then the woman was treated with combination chemotherapy (irinotecan, cisplatin) and a complete remission achieved in six months.

Breast cancer and lung cancer are the two most common malignancies in China. With the continuous improvement of breast cancer diagnosis and treatment technology, the survival time of breast cancer patients has been prolonged, and the number of breast cancer patients with second primary lung cancer (SPLC) has increased. In addition, breast cancer is the most common primary cancer in female patients with SPLC, and SPLC is the main cause of death in this population. More and more physicians pay attention to this clinical phenomenon. This paper summarized the risk and risk factors of SPLC in breast cancer patients, and elaborated its pathogenesis, in order to provide a theoretical basis for the clinical management of breast cancer patients and achieve accurate early intervention as soon as possible.

Cryptococcus neoformans commonly causes opportunistic infections in immunocompromised patients, especially in patients with AIDS. CD4+ T-lymphocytopenia in AIDS indicates an increased risk of opportunistic infection and a decline in immunological function. Idiopathic CD4 T-lymphocytopenia (ICL) is characterized by depletions in the CD4+ T-cell subsets, without evidence of HIV infection. Immunodeficiency can exist in the absence of laboratory evidence of HIV infection, and T-cell subsets should be evaluated in patients who present with unusual opportunistic infections. We report a case of pulmonary cryptococcosis and lung cancer in a patient with persistently low CD4+ cell counts, without evidence of HIV infection.

Pancreatic metastases are found in up to 40% of patients with small cell lung cancer, but metastasis-induced acute pancreatitis is rare. Treatment of metastasis-induced acute pancreatitis is initially supportive, but failure of conservative management are common. There are few reports on aggressive treatment with chemotherapy which lead to rapid clinical improvement and prolongation of survival in patients with metastasis-induced acute pancreatitis. We experienced a case of metastasis-induced acute pancreatitis in a patient with small cell lung cancer. Despite conservative treatment with dietary restriction and intravenous fluid supply, serum amylase levels increased persistently with severe abdominal pain. After chemotherapy with irinotecan and carboplatin, abdominal pain and serum amylase levels resolved dramatically.

BACKGROUNDIIIb-T(4) non-small cell lung cancer (NSCLC) is commonly considered a contraindication to surgery, although chemo-radiotherapy also achieves a poor survival rate. We reviewed our experience with T(4) NSCLC patients who underwent surgery to explore the indications and prognostic factors of surgical treatment of lung cancer invading the left atrium and great vessels.

METHODSWe investigated a cohort of 105 patients, 79 men and 26 women, who underwent surgery from May 1996 to July 2008. Their pathological staging was T(4)N(0)-(2)M(0). The median age was 59 years, ranging from 36 to 75 years. Patients were grouped based on invading sites: tumors invading the left atrium (LA group), tumors invading the superior vena cava (SVC group), and tumors invading the intrapericardial pulmonary artery (PA group). Patients were further characterized based upon the type of operation, complete resection and incomplete resection groups, and on the lymph node pathological status, N(0), N(1) and N(2) groups. We calculated the overall five-year survival rate.

RESULTSAll patients received resection of primary lesions, with partial resection of the left atrium in the LA group (n = 25), angioplasty of superior vena cava in the SVC group (n = 23) and intrapericardial ligation of the pulmonary artery in the PA group (n = 57). Complete resection was possible in 77 patients (73.3%). The overall survival rate of the 105 patients was 41.0% at 5 years; 36.0% for the LA group, 34.8% for the SVC group and 45.6% for the PA group. Pathological N status significantly influenced the overall 5-year survival rate; 61.5% for N(0), 51.1% for the N(1) and 11.8% for the N(2) groups (N(2) group versus N(0) group, P < 0.0001, N(2) versus N(1) group, P < 0.0001). Surgical resection also influenced survival; 49.4% for the complete resection group and 17.9% for the incomplete resection group (P < 0.0001). Cox regression analysis demonstrated that pathological N status was a significant independent predictor of prognosis.

CONCLUSIONSPathological N status is a significant independent predictor for survival of patients with IIIb-T(4) lung cancer invading the left atrium and great vessels. The completeness of resection has a significant influence on the overall 5-year survival rate. Surgery for T(4) lung cancer may be effective in patients without mediastinal lymph node involvement.

OBJECTIVETo investigate the clinicopathological characteristics and the prognosis of bladder neuroendocrine carcinoma (NEC).

METHODSClinicopathological data from 17 NEC of the bladder cases were collected, and immunohistochemical staining was performed with follow-up analysis and literature review.

RESULTSThe recruited included 13 male and 4 female patients, aged from 48 to 86 years old (average 61 years; 14 patients >60 years). Gross hematuria of the whole urination course or intermittent was the initial symptom. Macroscopically, the outer surface of the tumor presented with polypoid, lobulated, fungating or ulcerous structures. Histologically, according to the criteria of WHO classification of neuroendocrine tumor of the lung, our NEC cases were divided into three histological types: 13 cases of small cell carcinoma, 3 cases of large cell neuroendocrine carcinoma and 1 case of atypical carcinoid. The urothelial carcinoma was concurrent with NEC in 6 cases, and adenocarcinoma was concurrent with NEC in 2 cases. Most tumor tissue infiltrated to the muscular layer, some infiltrated to the outer membrane. Immunohistochemically, the positive expression rates of CD56, Syn and CgA were 16/17, 16/17 and 12/17, respectively. The epithelial markers, including CK7 and CKpan, were also expressed with positive rates of 12/17 and 15/17, respectively. TTF-1 was positively expressed in 11 cases. The follow-up data were available in 14 cases, of which 9 patients died of the tumor 1-34 months after surgery (average, 11 months). Five patients lived uneventfully for 1-12 months after surgery.

CONCLUSIONSNEC is a rare malignant tumor of the bladder. Immunohistochemical markers such as CD56, Syn, CgA and CKpan could be helpful in determining the diagnosis and differential diagnosis of the tumor. NEC is a highly invasive malignant tumor with poor prognosis. Based on its biological behavior, radical cystectomy is the preferred method of treatment for the tumor.

OBJECTIVE: To explore the relation between diabetes mellitus and clinicopathological factors and the incidence of radiation pneumonitis in patients with non-small cell lung cancer. METHODS: The data of 332 patients with non-small cell lung cancer, who were admitted to the Department of Oncology of Third Xiangya Hospital of Central South University between January 2007 and August 2009, were collected retrospectively. The patients were divided into a diabetes mellitus (DM) group (n=45) and a non-diabetes mellitus (NDM) group (n=287). The clinicopathological factors were compared between the two groups. The patients who received radiotherapy were further divided into a diabetes mellitus (DMR) group (n=33) and a non-diabetes mellitus group (NDMR) group(n=287), and the incidence of radiation pneumonitis was compared. RESULTS: A total of 45 patients (13.55%)developed diabetes mellitus. There was significant difference in the body-weight, age and hypertension (P<0.05), while no significant difference in the pathologic factors, such as tumor pathological type, degree of differentiation, and classification of malignant tumors (TNM) stage between the two groups(P>0.05). No significant difference in the irradiation area was found between the DM group and the NDM group(P>0.05). The incidence of radiation pneumonitis in the DMR group was 42.42%(14 out of 33), while 21.31%(39 out of 183) in the NDMR group, with significant difference in the incidence of radiation pneumonitis between the DMR group and the NDMR group(P<0.05). The risk value in the DMR group was 2.721 folds (95%CI, 1.253-5.910) that in the NDMR group in patients with non-small cell lung cancer companied with diabetes mellitus. CONCLUSION Diabetes mellitus is the risk factor of radiation pneumonitis for patients with nonsmall cell lung cancer who receive radiotherapy.

Although liver metastasis is commonly found in cancer patients, fulminant hepatic failure secondary to diffuse cancer infiltration into the liver is rare. Liver metastasis-induced fulminant hepatic failure has been reported in patients with primary cancer of the gastrointestinal tract, breast and uroepithelium, and in patients with melanoma and hematologic malignancy. Small cell lung cancer is so highly invasive that hepatic metastasis is common, but rapid progression to fulminant hepatic failure is extremely rare. We report here on a case of a patient who died because of rapid progression to fulminant hepatic failure as a result of hepatic metastasis of small cell lung carcinoma.

BACKGROUND: Malignant pleural effusion (PE) was generally defined as pleural effusion containing tumors with poor prognosis. Some kinds of undefined pleural effusions due to too small amount of effusion had poor prognosis too. This study aimed to analyze the clinical characteristics and prognostic factors of patients who suffered from limited-stage small cell lung cancer (LS-SCLC) complicated with pleural effusion. METHODS: A retrospective analysis included 542 patients who were diagnosed with LS-SCLC and had treatment in our hospital from October 2007 to January 2016. We had observed 109 patients who were diagnosed with pleural effusion at their first visit to the doctor. We analyzed the clinical characters, survival time and the prognostic factors of the 109 patients. Our main observation targets were overall survival (OS) and progression free survival (PFS). RESULTS: The median OS and PFS of whole group were 29.4 and 18.2 months. Before treatment, survival time of patients with PE were significantly shorter than patients without PE (median OS: 21.0 vs 31.7 months; median PFS: 14.1 vs 9.1 months; Log-rank, P=0.001, P=0.014). Multi-factor analysis of multivariate Cox shows PE was the independent prognostic factor of LS-SCLC (P=0.04). Single factor analysis showed factors affecting PE patient's survival time included clinical stages, lymph node (LN) stages, KPS scores, pulmonary atelectasis and the state of pleural after treatment. Cox multi-factor analysis reminded that the state of pleural effusion after treatment was the independent prognostic factor of LS-SCLC complicated with pleural effusion (P=0.016). There were three groups was apportioned patients without pleural effusion before treatment (group 1; n=433), patients whose pleural effusion disappeared after treatment (group 2; n=67) and patients whose pleural effusion didn't disappear after treatment (group 3; n=32).The median OS were 31.7, 23.2, 16.8 months in the group 1, 2, 3 and the median PFS were 19.1, 17.9, 11.4 months. Obvious difference was noted by the comparison of survival time of these three groups (Log-rank P<0.001, P<0.002). The difference between group 2 and group 3 was significant (Log-rank P=0.046, P=0.013) while no obvious difference was noted during comparison of group 1 and group 2. For patients who have LS-SCLC complicated with PE, there is no remarkable difference between chemoradiotherapy and chemotherapy alone. CONCLUSIONS The survival time of patients who suffered from limited-stage small cell lung cancer complicated with pleural effusion was obviously shortened. The disappearing of pleural effusion after treatment was the independent favorable prognostic factor of survival. How to treat needed further investigation.
