RESUMEN
AIM: We report the first prospective study of sunitinib for metastatic renal cell carcinoma (mRCC) in China. METHODS: Chinese mRCC patients received first-line sunitinib 50 mg daily (4/2 regimen). Overall survival (OS), progression-free survival (PFS), objective response rate and safety were assessed. Potential efficacy biomarkers were explored in post hoc analyses. RESULTS: Median PFS was 61.7 weeks; median OS was 133.4 weeks; objective response rate was 31.1%. Most frequent adverse events (AEs) were: hand-foot syndrome (63.8%), decreased white blood cell count (52.4%), fatigue (51.4%) and decreased platelet count (51.4%). AEs were identified that predicted longer PFS and OS. CONCLUSION: Sunitinib showed efficacy and manageable AE profile in treatment-naive Chinese mRCC patients. Larger prospective studies are required to confirm identified AEs as predictors of efficacy.

To investigate the initial symptoms, treatment, prognosis, and 1-, 3-, and 5-year survival of patients with bronchopulmonary carcinoid, clinical and pathological data were collected retrospectively from 74 patients diagnosed with bronchopulmonary neuroendocrine tumors at the Cancer Hospital, Chinese Academy of Medical Science, from January 2004 through December 2009. The data collected included age, initial symptoms, primary tumor sites, pathological types, lymphatic metastasis, and distant metastasis. The Kaplan-Meier method was used for survival analysis and the log-rank test was used for univariate analysis of prognostic factors. A Cox proportional hazard regression model was used for multivariate analysis. The 74 patients included 56 men and 19 women, and their average age was 56.07 years. The most common initial symptom was cough (51.35%), and the major lesion site was the left upper lobe of the lung (38.84%). Of the 59 patients (79.73%) who underwent surgery, most (76.27%) received a pulmonary lobectomy. The patients' 1-, 3-, and 5-year survival rates were 92.7, 80.3, and 71.9%, respectively. Univariate analysis showed that both local lymphatic and distant metastases were prognostic factors (P<0.05), whereas multivariate analysis showed that the pathological type (typical carcinoid and atypical carcinoid) was an independent prognostic factor (P=0.006). These data indicate that cough is the major presenting symptom of patients with bronchopulmonary carcinoid and the left upper lobe of the lung is the most commonly involved site. Following treatment, mostly by pulmonary lobectomy, the 5-year survival rate is 71.9%. The pathological tumor type is an independent prognostic factor.

BACKGROUND: Genitourinary embryonal rhabdomyosarcoma is rarely reported in China. This retrospective analysis aimed to characterize the clinicopathologic features and treatment outcomes of genitourinary embryonal rhabdomyosarcoma in a sample of Chinese patients. METHODS: Basic demographic and clinical data of 29 patients, who were diagnosed with genitourinary embryonal rhabdomyosarcoma between January 2000 and December 2011, were retrieved and analyzed. RESULTS: In these patients, 25 were males and 4 were females with a median age of 12 years. Paratesticule was the most common lesion site, followed by the prostate, bladder, and vagina. The median tumor size was 5.80 cm. Six patients had clinically positive regional nodes. At the initial diagnosis, patients had a metastatic disease. According to the TNM staging classification for the IRS-IV, phase I lesions were detected in ten cases, phase II lesions in six cases, phase III lesions in four cases, and phase IV lesions in nine cases. The median survival of all patients was 63 (range from 6 to 118) months. The 1-, 3-, and 5-year survival rates for these patients were 93%, 83%, and 52%, respectively. Multivariate analyses demonstrated that staging and anemia were significant predictors of prognosis. CONCLUSIONS: Our findings suggest that metastasis predicts a poor prognosis. Chemotherapy played an important role in comprehensive treatment. Palliative and neo-adjuvant chemotherapy could increase median survival time.

OBJECTIVE: To analyze the clinicopathologic factors related to recurrence and metastasis of stage II or III colon cancer after radical resection. METHODS: The clinical and pathological data of 628 patients with stage II or III colon cancer after radical resection from Jan. 2005 to Dec. 2008 in our hospital were retrospectively reviewed and analyzed. RESULTS: The overall recurrence and metastasis rate was 28.5% (179/628). The 5-year disease-free survival (DFS) rate was 70.3% and 5-year overall survival (OS) rate was 78.5%. Univariate analysis showed that age, smoking intensity, depth of tumor invasion, lymph node metastasis, TNM stage, gross classification, histological differentiation, blood vessel tumor embolus, tumor gross pathology, multiple primary tumors, preoperative and postoperative serum concentration of CEA and CA19-9, and the regimen of adjuvant chemotherapy were correlated to recurrence and metastasis of colon cancer after radical resection. Multivariate analysis showed that regional lymph node metastasis, TNM stage, the regimen of postoperative adjuvant chemotherapy, and preoperative serum concentration of CEA and CA19-9 were independent factors affecting the prognosis of colon cancer patients. CONCLUSION: Regional lymph node metastasis, TNM stage, elevated preoperative serum concentration of CEA and CA19-9, the regimen of postoperative adjuvant chemotherapy with single fluorouracil type drug are independent risk factors of recurrence and metastasis in patients with stage II-III colon cancer after radical resection.

OBJECTIVE: To investigate the epidemiology, diagnosis, and treatment status of neuroendocrine tumors (NETs) in our hospital. METHODS: Medical records of 252 patients with neuroendocrine tumors diagnosed and treated in our hospital from January 1, 2004 to December 31, 2009 were collected and retrospectively reviewed in this study. The clinicopathological data including age of onset, initial symptoms, primary site, pathological conditions (Sny, CgA, Ki-67), disease stage at diagnosis, treatment, and follow up were analyzed. RESULTS: The gender ratio M/F of the 252 cases was 1.9:1, with mean age of 55.2 years, and the high incidence was in age of 60-69 years. The tumors were located in the gastrointestinal tract (117 cases, 46.4%), broncho-pulmonary system (74 cases, 29.4%), other sites (61 cases, 24.2%) and unknown primary site (2 cases, 0.8%). Their first clinical symptoms vary, depending on the primary site. The common symptoms of primary rectal NETs were changes in bowel habits (29.3%) and diarrhea or constipation (17.5%), and most gastric NETs presented epigastric discomfort (86.4%). Most patients (71.4%) were diagnosed with stage I, II, III disease. Among the 252 cases, there were 110 carcinoids (43.7%), 108 neuroendocrine carcinomas (42.9%), 23 atypical carcinoids (9.1%), five neuroendocrine tumors (2.0%), four Merkel cell tumors (1.6%), and two composite carcinoids (0.8%). 206 patients (81.7%) received surgery, 39 (15.5%) received chemotherapy, and 31 cases (12.3%) were treated by palliative radiotherapy. CONCLUSIONS: This single-center retrospective analysis of data demonstrated that males have a higher incidence rate than females. The most common primary sites of NETs are the digestive tract and lungs. The initial symptoms of NETs are different depending on their primary sites. Good prognosis can be achieved in the majority of patients after surgery, chemotherapy and palliative radiotherapy.

OBJECTIVE: The combination of oxaliplatin and S-1 is effective in patients with advanced gastric cancer. The purpose of this study was to analyze the safety and compliance of this combination regimen as adjuvant chemotherapy in patients with gastric cancer. METHODS: Clinical data of 71 patients with gastric cancer treated with oxaliplatin plus S-1 as adjuvant chemotherapy in the Cancer Hospital, Chinese Academy of Medical Sciences (CAMS) from Jan 1(st), 2010 to Jan 1(st), 2012 were retrospectively reviewed. The types and incidence rate of adverse events related to chemotherapy and the results of follow up of the patients were analyzed. RESULTS: Among the 71 cases, 17 were treated with oxaliplatin biweekly, while 54 with oxaliplatin triweekly. The most common adverse events were neutropenia (n = 49, 69.0%), nausea/vomiting (n = 51, 71.8%), and anorexia (n = 49, 69.0%). The most frequent grade 3-4 toxicities were neutropenia (n = 13, 18.3%), thrombocytopenia (n = 10, 14.1%), anorexia (n = 5, 7.0%) and nausea/vomiting (n = 4, 5.6%). Seven (87.5%) of the 8 patients previously treated with neoadjuvant chemotherapy experienced thrombocytopenia in the postoperative adjuvant chemotherapy, and four (50%) of the 8 patients experienced grade 3-4 thrombocytopenia. The rates of grade 3-4 adverse events in patients aged 65-years or older were similar to that in younger patients. CONCLUSIONS: The combination of oxaliplatin and S-1 used as adjuvant chemotherapy is well tolerated by patients with gastric cancer. Neutropenia, thrombocytopenia, nausea/vomiting and anorexia are the major treatment-related adverse events. Patients who received neoadjuvant chemotherapy do not well tolerate this regimen as postoperative adjuvant chemotherapy. This combination regimen has a manageable tolerability profile in adjuvant setting in patients ≥ 65 years old.

OBJECTIVE: To evaluate the efficacy and safety profile and to explore the role of docetaxel, S-1 plus cisplatin (DCS) or oxaliplatin (DOS) in the treatment of advanced gastric cancer. METHODS: A total of 45 patients with advanced gastric cancer were recruited. They received DCS or DOS at the discretion of investigators. Docetaxel was given intravenously at the dose of 60 mg/m² at d1, S-1 60 mg×m⻲×d⻹ or 80 - 120 mg/d according to individual patient's area of body surface orally from d1 to d14 and cisplatin 30 mg/m² at d1, d2 or oxaliplatin 111 - 127 (median: 117) mg/m ²at d2. Each cycle was for 21 days. RESULTS: Forty-three patients received ≥ 1 complete cycle of DCS/DOS with a median cycle number of 5(range: 1 - 8). Among 42 patients evaluated for efficacy, the outcomes were partial response (n = 28), stable disease (n = 9) and progression (n = 5). The response rate was 66.7%. Progression-free survival (PFS) of 32 patients on chemotherapy alone was 7.1 months and the median overall survival (OS) was not reached. The most common grade 3/4 adverse effects included neutropenia (46.5%), thrombocytopenia (9.3%), vomiting (9.3%), nausea (7.0%) and diarrhea (4.7%). Ten of fourteen patients with advanced unresectable gastric cancer without clinically detectable distant metastases underwent surgical resection after a median of 4 (2-6) cycles of DCS or DOS and 9 (64.3%) had R0 resection. CONCLUSIONS: DCS/DOS is effective for advanced gastric cancer and in the setting of neoadjuvant chemotherapy. And the toxicities of DCS/DOS are manageable.

OBJECTIVE: To analyze the outcome of platinum analogue-based chemotherapy for advanced esophageal squamous cell carcinoma (ESCC) patients treated in Cancer Hospital of Chinese Academy of Medical Science. The association of response rate or OS and the clinical-pathological factors were analyzed as well. METHODS: Clinical data of 134 advanced ESCC were retrospectively analyzed from January 1999 to August 2008 in our hospital. All of these chemo-naive patients received platinum analogue-based chemotherapy. The association of response rate or OS and the clinical-pathological factors were analyzed. RESULTS: The median age of all the 134 patients was 58 years old. The ratio of male and female was 7.9:1. A total of 450 cycles (median: 3 cycles) of chemotherapy was completed. 91 (67.9%) of these patients received cisplatin-based regimens. The overall response rate was 31.3%, and cisplatin-based regimens were better than other platinum analogue-based regimen, but there was no significant difference (36.3% vs 20.9%, P = 0.075). The median follow-up time was 44 months (range 8 - 120). The median TTP was 4 months (range 1 - 43), and median survival time was 8 months (range 1 - 43). The 1 year and 2 year survival rate was 36.2% and 17.5%, respectively. According to univariate analysis, there was a worse prognosis when patients with multiple primary site, well-differentiated tumor, more than one site of metastasis, fail to achieve responses, TTP ≤ 4 months and received less than 2 cycles of chemotherapy. Multivariate analysis showed that TTP ≤ 4 months was the only independent prognostic factor for this group of patients. CONCLUSIONS: Platinum analogue-based chemotherapy was the standard of care for advanced ESCC. There was a trend to improve the outcomes with platinum analogue combined with new drugs. Randomized trial with large samples was need.

BACKGROUND: Extensive-stage small cell lung cancer (ES-SCLC) is deemed as a fatal malignancy with a poor prognosis. Although immunotherapy has gradually played an important role in the treatment of ES-SCLC since 2018, ES-SCLC treatment data and patient outcome before 2018, when chemotherapy served as a fundamental therapeutic strategy, is still meaningful as a summary of the situation regarding previous medical treatment and is a baseline for comparative data. In addition, the prognostic factors of ES-SCLC have failed to reach a consensus until now. Therefore, this study aimed to evaluate survival and identify the prognostic factors in an ES-SCLC population. METHODS: We retrospectively collected the detailed medical records of 358 patients with ES-SCLC from January 1, 2011 to December 31, 2018 in a Chinese top-level cancer hospital. The prognostic factors were evaluated by Cox univariate and multivariate analysis. RESULTS: The median overall survival (OS) of ES-SCLC patients (N = 358) was 14.0 months, the one- and two-year OS rates were 56.2% and 21.7%, respectively. Moreover, we identified two demographic characters (age ≥ 70, smoking index ≥ 400), one tumor burden factor (bone multimetastasis), two tumor biomarkers (cyfra211, CA125) and two laboratory indexes (decreased Na, PLR < 76) as independent prognostic factors for OS in this patient population. Progression-free survival (PFS) data of 238 patients was obtained for further analysis, and the median PFS was 6.2 months, and six-month and one-year PFS rates were 51.7% and 14.3%, respectively. Elevated cyfra211, decreased Hb and Na were identified as independent prognostic factors for PFS. CONCLUSIONS: This study provides real-world evidence of the survival and prognosis of ES-SCLC patients which will enable better evaluation and clinical decision-making in the future.

OBJECTIVE: To investigate the potential prognostic factors for patients with liver metastases from colorectal cancer treated with different modes of therapy. METHODS: The clinicopathological data of 300 patients with liver metastases from colorectal cancers were retrospectively reviewed and analyzed. RESULTS: The median survival of patients with recurrence (MSR) treated with complete and palliative resection of liver metastases and unresectable patients was 48, 19 and 18 months, respectively (P = 0.000). In patients with unresectable liver metastases, systemic chemotherapy plus regional therapy demonstrated a median survival time of 23 months, significantly longer than the 6 months in untreated patients (P = 0.000). Patients who showed response to the first-line therapy demonstrated an improved survival versus the patients who had no response, with a median survival time of 24 vs. 16 months (P = 0.000). Univariate analysis revealed that resection modes of primary diseases and liver metastases, treatment modality for liver metastases, and response to first-line therapy were prognostic factors. Multivariate analysis showed that resection modes of liver metastases, multimodality treatment after liver metastases, and the response to first-line therapy were all independent prognostic factors for patients with liver metastases from colorectal cancer. CONCLUSION: Resection of liver metastases, multimodality treatment after liver metastases, and response to first-line chemotherapy are all independent prognostic factors for patients with liver metastasis from colorectal cancer.

OBJECTIVE: The extrapulmonary small cell carcinoma (EPSCC), a uncommon malignant tumor, has seldom been reported. The aim of this study was to analyze the clinical characteristics, treatment and prognosis of EPSCC. METHODS: The clinical data of 243 patients admitted in our hospital from 1977 to 2007 were reviewed. The survival rate was calculated by the Kaplan-Meier method and log-rank test. RESULTS: The median age of the patients was 58 years and the male-to-female ratio was 2.47:1. According to VALSG criteria, 209 patients had limited disease (LD) and 34 had extensive disease (ED). 170 patients received chemotherapy-based multimodal therapy, 73 received surgery, and/or radiotherapy. The 6, 12, 24, 36 and 60-month survival rates of these patients were 88.9%, 67.2%, 36.8%, 27.3% and 18.3%, respectively. The clinical stage, vessel involvement and regional lymph node metastases were independent prognostic factors of EPSCC. Patients with LD had a median overall survival of 18.6 months compared with 14.0 months in patients with ED (P = 0.030). The median survival was 19.2 months for the patients without vessel involvement and 14.4 months with vessel involvement (P = 0.026). The median survival of the patients with regional lymph node metastases was 13.9 months, while 39.5 months without regional lymph node metastases (P = 0.000). Among different primary sites, patients with gynecologic small cell cancer had a median survival of 28.0 months, head and neck 20.1 months and gastrointestinal tract 14.3 months. Brain metastasis was observed in a lower number of patients with EPSCC compared with that in patients with SCLC. There were no statistically significant differences in overall survival between patients with pure and mixed EPSCC (P = 0.396). CONCLUSION: EPSCC is an uncommon malignant tumor with early metastasis and poor prognosis. The clinical characteristics of EPSCC and SCLC were similar in some aspects, however, there are some differences in etiology, clinic course, survival and frequency of brain metastases. These differences may influence the choice of therapeutic strategy. Multimodal therapy, combination of chemo- and radio-therapy after surgical resection may improve the outcome of EPSCC.

BACKGROUND AND OBJECTIVE: There is a mounting evidence of the role of HER2 overexpression inpatients with gastric cancer, and it has been solidly correlated with poor outcomes and more aggressive diseases. This study was to investigate the relationship between the expression of HER2/neu and the clinical characteristics of advanced gastric carcinomas, including survival. METHODS: The clinical data of 83 patients admitted in Cancer Hospital, Chinese Academy of Science, from 2006 to 2008 were reviewed. The HER2/neu status in 83 advanced gastric carcinomas was evaluated using immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). The survival rate was calculated by Kaplan-Meier method and the log-rank test using SPSS13.0 software. RESULTS: The median age of the patients was 60 years and the male-to-female ratio was 2.95:1. HER2/neu overexpression (2+ and 3+) and amplification were found in 25 (30.1%) and 29 (34.9%) advanced gastric carcinomas, respectively. HER2/neu amplification/overexpression was associated with worse survival in patients with advanced gastric carcinoma. The median survival of the patients without HER2/neu amplification was 12.6 months and that of those with HER2 amplification was 5.5 months. CONCLUSIONS: HER2/neu status may be a clinical predictor of prognosis in advanced gastric cancer patients.

OBJECTIVE: To analyse the clinical characteristics and potential prognostic factors of colorectal cancer patients with liver metastases. METHODS: The clinical and pathological data of 300 colorectal cancer patients with liver metastases were retrospectively reviewed and analyzed. RESULTS: The median survival time of these patients was 19.0 months. The 1-, 2- and 5-year survival rates after liver metastases were 79.0%, 29.0% and 3.0%, respectively. Univariate analysis revealed that performance status (KPS), histological grading, primary tumor, N status, lymphatic and vascular invasion, stage at diagnosis, the number, size and distribution of liver metastases and other accompanied metastases were prognostic factors. Multivariate analysis showed that KPS, lymphatic and vascular invasion, the number and size of liver metastases were independent prognostic factors of colorectal cancer with liver metastases. CONCLUSION: Performance status, lymphatic and vascular invasion, the number and size of liver metastases are independent prognostic factors of colorectal cancer with liver metastases.

OBJECTIVE: To investigate the prognostic factors and the principles of treatment of primary esophageal small cell carcinoma (SCEC) retrospectively. METHODS: The data of 126 patients with histologically confirmed SCEC treated in our department between May 1985 and June 2005 were retrospectively analyzed. 85 patients were in limited disease stage (LD) and 41 patients as extensive disease stage (ED) according to the Veterans Administration Lung Study Group staging system. Among the 84 patients treated with esophagectomy, 8 cases were in stage I, 16 in stage IIa, 10 in stage IIb, 40 in stage III, 4 in stage IVa and 6 in stage IVb, according to the TNM system (6(th) edition, AJCC). Cox's hazard regression model was used to identify the prognostic factors, and Chi-square test to detect the difference of frequencies among different groups. Kaplan-Meier and log-rank methods were used to estimate and compare the survival rates. RESULTS: The median follow-up duration of this series was 13 months. One hundred and eight patients died of the disease during the follow-up, 10 were still alive and 8 were lost to follow-up. The 1-, 3-, and 5-year overall survival rates (OS) were 52.2%, 15.9%, and 12.2%, respectively, with a median survival time (MST) of 12.5 months. The 1-, 2-, and 3-year OS were 62.1%, 30.8%, and 22.4% with a MST of 14.0 months for LD, and 29.3%, 13.6% and 2.7% with a MST of 7.0 months for ED, respectively. There was a statistically significant difference in OS between LD and ED (P = 0.0001). The MST of the patients treated with chemotherapy was 14.5 months, significantly longer than the 5.2 months of the patients without (P = 0.0001). Multivariate analysis showed that stage (HR 1.91, 95% CI 1.26 approximately 2.91, P = 0.002), length of the primary lesion (HR 1.75, 95% CI 1.17 approximately 2.63, P = 0.007), and chemotherapy (HR 0.42, 95% CI 0.28 approximately 0.65, P = 0.000) were independent prognostic factors. CONCLUSION: Esophageal small cell carcinoma is a systemic disease. The tumor stage (LD or ED), length of the primary lesion and chemotherapy are independent prognostic factors. Therefore, a systemic therapy based on chemotherapy should be recommended.

OBJECTIVE: To retrospectively analyze and compare the treatment efficiency of CHOP-based regimens with or without high-dose consolidation treatment combined with hematopoietic stem cell transplantation (HDT-HSCT) in the patients with lymphoblastic lymphoma (LBL). METHODS: From 1989 to 2004, totally 63 patients with LBL were initially treated with a standard CHOP-based regimen. Forty-two of the 63 patients achieved complete response (CR), 26 of those subsequently received consolidation HDT-HSCT, while the other 16 had 6-8 cycles of standard CHOP-based treatment only. RESULTS: Of the 63 patients, 57 had a T-LBL and 6 B-LBL, with a median age of 20 years, 19 (30.2%) had a stage I-II diseases and 44 (69.8%) stage III-IV diseases, 61.9% presented with a mediastinal mass. Bone marrow involvement presented in 28.6% of the patients. Fourteen percent had central nervous system involvement. The median follow-up period was 24 months, and the estimated 5-year overall survival and disease-free survival of this series was 31.2% and 29.3%, respectively. Of the 42 patients who achieved CR, the 5-year OS rate of the patients who received HDT-HSCT as a consolidation therapy was 59.8% versus 14.6% of the patients treated by CHOP-based regimens alone (P=0.004). Bone marrow involvement, age > or =20 years, short response duration and primary refractory disease were factors significantly associated with poor outcome. Among the 18 patients with bone marrow involvement, 3 received allogeneic HSCT and were all still alive at the follow up time of 22, 32 and 37 months, respectively, while another 4 received auto-HSCT and all died of the disease within 14 months. CONCLUSION: Short term treatment with a CHOP-based regimen is not sufficient for the patients with lymphoblastic lymphoma. High-dose consolidation treatment and hematopoietic stem cell transplantation may improve overall survival and disease free survival. Bone marrow involvement, age >20 years, and short response duration and primary refractory disease are all the factors significantly associated with poor outcome. For the patients with bone marrow involvement, allohematopoietic stem cell transplantation is superior to auto-hematopoietic stem cell transplantation.

OBJECTIVE: To evaluate the clinical characteristics, treatment and prognostic factors in patients with primary small cell carcinoma (SmCC) of the esophagus. METHODS: Eighty-one esophageal SmCC patients were treated from 1999 to 2007 in our department, and their clinical data were retrospectively reviewed. RESULTS: Of the 81 patients, 52 (64.2%) were in limited stage (LS) and 23 (28.4%) in extensive stage (ES). The 1-, 3- and 5-year survival rates were 55.6%, 6.2% and 2.5%, respectively, with a median survival time of 13.5 months for the whole group; 69.2%, 7.3% and 3.6%, respectively, with a median survival time of 15 months for the LS group; while only 25.2%, 0 and 0, respectively, with a median survival time of 6 months for the ES group. Multivariate analysis showed that disease stage, performance status, multidisciplinary comprehensive therapy and mode of treatment were independent prognostic factors. CONCLUSION: Esophageal small cell carcinoma is a rare but highly aggressive malignant tumor. Disease stage and performance status are important prognostic factors. Appropriate treatment may play a key role in improving the survival of the patients.

OBJECTIVE: To analyze the correlation of long-term survival with the treatment strategies in patients with testicular seminoma. METHODS: Clinical data of 294 patients with testicular seminoma treated in our hospital between 1959 and 2004 were collected and analyzed. The median age of the patients was 37 years (range 13 - 70 years). Among them, 260 were in stage I disease, 16 in stage II, and 18 in stage III. The patients were treated by surgical resection plus chemotherapy and/or radiotherapy. The survival rate was calculated using Kaplan-Meier method and log-rank test using SPSS 13.0 software. RESULTS: The overall 5-, 10-, 20- and 30-year survival rates in this series were 92.1%, 91.8%, 85.5% and 71.4%, respectively. The major prognostic factor was found to be clinical stage. The patients with adjuvant chemotherapy after orchiectomy had better 10-year survival than the patients without (97.5% vs. 79.2%, P = 0.001). For stage II/III patients, the patients with chemotherapy and the patients with chemotherapy plus radiotherapy had a similar progression-free survival (PFS) and overall survival (OS) (P > 0.05). CONCLUSION: Testicular seminoma is sensitive to chemotherapy and radiotherapy, and a good cure rate can still be achieved in the relapsed patients with a salvage treatment. Therefore, wide excision and long-term chemotherapy should be avoided in order to maintain the quality of life in those patients.

OBJECTIVE: To assess the polymorphism of UGT1A gene in Chinese, and to investigate the correlation between UGT1A polymorphism and irinotecan toxicity in colorectal cancer patients. METHODS: 70 patients with advanced colorectal cancer were treated with irinotecan and 5-fluorouracil. Polymorphism analysis was performed in all those patients and 100 healthy subjects. Genomic DNA was extracted from peripheral blood and genotyped using polymerase chain reaction and direct sequencing. RESULTS: 14 patients exhibiting grade 3 - 4 neutropenia (20.0%), 16 patients experienced grade 2 - 4 diarrhea (22.9%), including only 4 patients with grade 3 - 4 diarrhea (5.7%). Compared with TA6/7 and TA7/7, UGT1 A1 * 28 wild genotype TA6/6 was significantly associated with reduced toxicity (42.1% vs. 15.7%, P = 0.027). There was no significant difference in the distribution of UGT1A genotypes between colorectal cancer patients and healthy subjects. CONCLUSION: Chinese patients exhibit less irinotecan-related diarrhea due to higher frequence of UGT1A A1 * 28 wild genotype TA6/6.

OBJECTIVE: Recent studies have reported increased mortality for right-sided colon cancers; however, the results are conflicting for different stage tumors. We examined the differences in clinicopathology between right- and left-sided colon cancers and the relationships between colon cancer location (right- and left-side) and 5-year disease-free survival (DFS) and overall survival (OS). METHODS: We identified patients from 2005 to 2008 with stage II/III colon cancer who underwent surgery for curative intent. We explored the impact of the tumor location on the postoperative DFS and OS using univariate and multivariate analyses. RESULTS: Of 627 patients, 50.6% (317/627) had right-sided colon cancer. These patients were more likely to have weight loss, second primary tumor, elevated preoperative carbohydrate antigen 19-9 (CA19-9), increased incidence of non-adenocarcinoma, more poorly differentiated tumors, vascular invasion, defective mismatch repair, and a lighter smoking history (P < 0.05). Right-sided colon cancer had a higher recurrence incidence compared with left-sided cancer (30.6% vs. 23.2%, P = 0.037), particularly with multiple metastatic sites in the first recurrence (17.5% vs. 5.6%, P = 0.020). Kaplan-Meier survival curves demonstrated a significant difference in the 5-year DFS rate between right- and left-sided cancers across all stages (68.1% vs. 75.2%, P = 0.043). However, there was no significant difference in the 5-year OS rate between the two groups (73.8% vs. 79.0%, P = 0.103). Subgroup analysis demonstrated that patients with left-sided colon cancer had a significantly better 5-year DFS and OS rates compared with those with right-sided disease at stage III (64.3% vs. 46.8%, P = 0.002; 69.5% vs. 53.5%, P = 0.006, respectively); there were no significant differences in the 5-year DFS and OS rates at stage II (85.2% vs. 85.9%, P = 0.819; 89.8% vs. 88.5%, P = 0.803, respectively). Adjusted Cox regression analysis showed no significant differences in the 5-year OS and DFS rates for stage II [hazard ratio (HR) = 1.203, 95% confidence interval (CI): 0.605-2.391, P = 0.598; HR = 0.980, 95% CI: 0.542-1.774, P = 0.948, respectively] or all stages combined (HR = 0.867, 95% CI: 0.613-1.227, P = 0.421; HR = 0.832, 95% CI: 0.606-1.142, P = 0.255, respectively). However, stage III left-sided cancer had higher 5-year OS and DFS rates (HR = 0.626, 95% CI: 0.414-0.948, P = 0.027; HR = 0.630, 95% CI: 0.428-0.926, P = 0.019, respectively). CONCLUSION: We found that right- and left-sided colon cancers had significantly different clinicopathological characteristics. Right-sided colon cancer had a higher incidence of recurrence than left-sided disease. Patients with stage III right-sided colon cancer had a worse prognosis compared with those with stage III left-sided colon cancer.
