Background: Approximately 25% of patients with colorectal cancer present synchronous metastases, most frequently located in the liver. Aims: The assessment of optimal therapeutic strategies for the primary tumor in such patients. Methods: We analyzed the outcomes of 209 patients who underwent simultaneous or delayed resection of the primary tumor and liver metastases, the survival rates of patients with initially unresectable liver metastases that were rendered resectable, and the prognostic factors related to the primary tumor. Results: The outcomes of simultaneous resections were similar to those of delayed resection. In patients with initially unresectable liver metastases that were rendered resectable, the survival rates were similar to those of patients with initially resectable metastases. The survival rate of N2 patients was significantly lower than those of N1 and N0 patients. Conclusions: Simultaneous resection provides a safety profile and survival rate similar to that of delayed resection. The N category allows for prognostic estimation in metastatic colorectal patients.

574 Background: Peritoneal metastasis (PM) in patients diagnosed with colon cancer is associated with a poor prognosis. We aimed to analyze prognostic factors associated with PM in patients diagnosed with colorectal cancer (CRC). Methods: We evaluated 237 patients who underwent surgery between 2002 and 2016 for CRC with PM. The extent of PM was evaluated using the Peritoneal Cancer Index (PCI). Clinicopathological variables, PCI score, surgical curability, and the administration of postoperative chemotherapy were evaluated. Overall survival was analyzed using the Kaplan-Meier method. Multivariate analysis was performed to assess the prognostic value of these variables, using the Cox regression model. Results: Our patients included 119 men and 118 women with a median age of 64 (range: 21–90) years. The primary tumor sites were the right-sided colon (n = 103), left-sided colon (n = 84), and rectum (n = 50). The median PCI score was 4 (range: 1–30). Synchronous PM was detected at the time of diagnosis of the primary tumor in 165 patients (69.6%). Distant metastases except peritoneal metastases was detected in 137 patients (57.8%). R0 resection was performed in 62 patients (19.0%). Postoperative chemotherapy was performed in 165 patients (69.6%). The median survival time in all patients was 19.4 (range: 0–30) months, and the five-year overall survival rate was 16.3%. Multivariate analysis revealed that PCI ≤ 5 (hazard ratio [HR]: 2.56, 95% confidence interval [CI]: 1.56-4.32, P < 0.01); the absence of distant metastasis, except peritoneal metastasis (HR: 1.65, CI: 1.15-2.40, P < 0.01); R0 resection (HR: 4.21, CI: 2.44-7.50, P < 0.01) affected the survival rate. Conclusions: Our results show that a low PCI, the absence of distant metastasis except peritoneal metastasis, and R0 resection are prognostic factors in patients diagnosed with PM-CRC.

If KRAS mutation status of primary colorectal tumor is representative of corresponding colorectal liver metastases (CRLM) mutational pattern, is controversial. Several studies have reported different rates of KRAS discordance, ranging from 4 to 32%. Aim of this study is to assess the incidence of discordance and its impact on overall survival (OS) in a homogenous group of patients. KRAS mutation status was evaluated in 107 patients resected for both primary colorectal tumor and corresponding CRLM at the same institution, between 2007 and 2018. Discordance rate was 15.9%. Its incidence varied according to the time interval between the two mutation analyses (p = 0.025; Pearson correlation = 0.2) and it was significantly higher during the first 6 months from the time of primary tumor evaluation. On multivariable analysis, type of discordance (wild-type in primary tumor, mutation in CRLM) was the strongest predictor of poor OS (p < 0.001). At multivariable logistic regression analysis, the number of CRLM >3 was an independent risk factor for the risk of KRAS discordance associated with the worst prognosis (OR = 4.600; p = 0.047). Results of our study suggested that, in the era of precision medicine, possibility of KRAS discordance should be taken into account within multidisciplinary management of patients with metastatic colorectal cancer.

Little is known about breast cancer in Vietnamese women. Previous studies have reported the frequencies of prognostic factors of breast cancer in this population. The aim of this study was to examine the prognostic factors associated with the survival rates of patients with breast cancer treated at the National Cancer Hospital, Hanoi, Vietnam. We recruited 248 women with operable breast cancer treated with surgery and adjuvant therapy. Tumor tissue samples were stained by many immunohistochemical approaches and analyzed for estrogen receptor, progesterone receptor, and HER2 gene amplification status. A Cox model was used to determine the relationship between survival and the prognostic factors. The disease-free survival rate, overall survival rate, and cancer-specific survival rate were 75.8%, 80.6%, and 86.4%, respectively, at 5 years and 62.3%, 68.1%, and 78.9%, respectively, at 10 years. The lung was the most common metastatic site. Women with factors associated with a poor prognosis (eg, advanced clinical stage, high tumor grade, progesterone receptor [PR] negativity, HER2 amplification) had significantly lower survival rates. Patients with PR-negative breast cancer had significantly worse survival rates compared to those who were PR positive, according to multivariate analysis (hazard ratio = 1.77, 95% confidence interval: 1.01-3.11, P = .045); however, there was only a statistically significant difference in postmenopausal patients. The PR was a prognostic factor in postmenopausal women with breast cancer, but not in premenopausal women.

ObjectiveTo analyze the therapeutic effect and prognostic factors of nasopharyngeal carcinoma (NPC) patients with distant metastases at initial diagnosis receiving induction chemotherapy with intensity-modulated radiotherapy (IMRT).MethodsA total of 129 patients who underwent platinum-based induction chemotherapy followed by definitive IMRT with or without concurrent or adjuvant chemotherapy for newly diagnosed distant metastatic NPC in our center between March 2008 and November 2018 were retrospectively analyzed. 41 patients underwent local therapy for metastatic sites. Kaplan-Meier method was used to estimate survival rates, Log-rank test and Cox proportional hazards model were used to figure out independent prognostic factors of overall survival (OS).ResultsA total of 66 patients had been dead (median follow-up time, 51.5 months). The median overall survival (OS) time was 54.2 months (range, 7-136 months), and the 1-year, 2-year, 3-year, 5-year overall survival rates were 88.0%,71.0%,58.0%, and 47.0%. Multivariate analysis found that the factors correlated with poor overall survival were pre-treatment serum lactate dehydrogenase (SLDH) &gt;180U/L, chemotherapy cycles&lt;4, and M1 stage subdivision (M1b, single hepatic metastasis and/or multiple metastases excluding the liver; and M1c, multiple hepatic metastases). The 5-year OS rates for M1a, M1b and M1c were 62.6%,40.4% and 0%, respectively.ConclusionPlatinum-containing induction chemotherapy combined with IMRT seemed to be advantageous to prolong survival for some NPC patients with synchronous metastases at initial diagnosis. The independent factors to prognosticate OS were pre-treatment SLDH, number of chemotherapy cycles, and M1 subcategories. Prospective clinical trials are needed to confirm the result.

Abstract Background Stage IV colorectal cancer (CRC) patients are heterogeneous with distinctive clinicopathologic features and prognosis. Radical resection of primary tumor and distant metastases is associated with improved survival outcomes in metastatic CRC. The value of palliative primary tumor resection is controversial. The present study explored which subgroups benefited more from primary tumor resection in metastatic CRC. Methods Between 2004 and 2015, patients with metastatic CRC were identified using the surveillance, epidemiology, and end results (SEER) database. Uni- and multivariable Cox regression analysis were performed to identify factors associated with decreased cancer-specific mortality. The subgroups were divided based on the independent prognostic factors. Results Age, marital status, race, serum CEA, histologic type, differentiation, tumor location, surgery of primary or metastatic lesion, site of metastases, number of metastatic sites, chemotherapy and radiotherapy were identified as independent prognostic factors. Patients with non-white race, normal serum CEA, non-signet ring cell carcinoma, well or moderate differentiation, surgery of metastases, isolated liver metastasis, single metastasis, receiving chemotherapy or radiotherapy presented more survival benefit from primary tumor resection. Conclusion Subgroup of metastatic CRC optimizes decision-making and selected patients will benefit more from primary tumor resection.

Abstract One hundred forty-seven patients with Ann Arbor stages I and II diffuse large cell lymphoma (DLCL) were treated with combination chemotherapy consisting of cyclophosphamide, doxyrubicin, prednisone, and low-dose bleomycin (CHOP-Bleo) and involved-field radiation (IF XRT) between 1974 and 1984. A complete remission (CR) was attained by 54 of 57 patients with stage I disease and by 78 of 90 patients with stage II disease. Thirty-five patients had relapsing disease that occurred within 3 years in 31. The overall 10-year survival rate, counting all deaths, for patients with stage I was 72% as compared with 43% for patients with stage II (P less than .01). Determinate survival rates, censoring eight unrelated deaths, were similar to the overall survival rates: 77% and 51%, respectively. A multivariate analysis identified three independent prognostic factors: age, tumor extent, and serum lactic dehydrogenase (LDH) level. When the combined effect of tumor extent and LDH level were taken into consideration in the analysis, three risk groups for survival were identified. The best group, which consists of patients with minimum tumor and normal LDH levels, had a 10- year determinate survival of 79%. Patients with extensive tumors and elevated LDH levels had the poorest survival rate of 44%. An intermediate-risk group with a determinant survival of 62% was composed of patients with either extensive tumors or elevated LDH levels. These differences demonstrate the need to develop different treatment strategies based on risk factors for survival for patients with apparently localized Ann Arbor stages I/II DLCL.
