PCV for Oligodendroglial Tumors: In Search of Prognostic Factors for Response and Survival

Background:We report survival and pretreatment prognostic factors for survival and chemosensitivity in 53 oligodendrogliomas treated with PCV (procarbazine, lomustine and vincristine) chemotherapy.Methods:A total of 53 patients with histologically proven oligodendroglioma, anaplastic oligodendroglioma or oligo-astrocytoma and treated with PCVwere extracted from the London Regional Cancer Center database. A retrospective review was conducted to evaluate overall survival and pretreatment prognostic factors for survival and chemosensitivity.Results:The median survival time from diagnosis was 123.6 months. The overall five- and ten-year survival rates were 72.7% and 52.7% respectively. Age <40, seizure as an initial symptom, absence of cognitive deficit and presence of a homogeneous hypodense lesion without contrast enhancement on the initial pretreatment CT scan were all factors independently associated with favorable outcome. The presence of increased cellularity, pleomorphism, mitosis, vascular proliferation and grading as an anaplastic lesion using these surrogates on pathological assessment, were all associated with an unfavorable outcome in univariable analysis. In multivariable analysis, only the anaplastic grading and presence of increased cellularity were significant determinants of unfavorable survival. The only factor adversely associated with chemosensitivity was the presence of a focal symptom at presentation.Conclusion:Overall survival is significantly longer in oligodendroglial lesions than in fibrillary astrocytic tumors. A two tier grading system using standard morphological features seems accurate in predicting outcome in these patients. The presence of a neoplastic astrocytic component does not seem to impact the outcome. No clinical, radiological or pathological factor could be identified to reliably predict chemotherapy response.

Clinicopathologic Characteristics

Background/Aims: Alpha-fetoprotein-producing colorectal cancer (AFPP-CRC) is quite rarely seen. This study aimed to elucidate the clinicopathologic characteristics and prognostic factors of AFPP-CRC. Methods: Among 5,051 colorectal cancer patients receiving surgery in the Fudan University Shanghai Cancer Center from 2006 to 2016, we identified 78 patients with elevated serum level of AFP (> 10 µg/L) preoperatively. A propensity score matching (PSM) analysis was performed which matched 75 AFPP-CRC patients to the same number of AFP-negative colorectal cancer (AFPN-CRC) patients. Kaplan-Meier curves were compared using the log-rank test and multivariable analysis was performed to evaluate the effect of AFP-positivity while adjusting confounding factors. 27 patients were available for immunohistochemical analysis. We conducted functional experiments to characterize the tumorigenicity of AFP. Results: Patients with AFPP-CRC had a significantly higher incidence of advanced TNM stage and liver metastasis. Overall survival was significantly different between two groups before and after PSM, and AFP-positivity was one of the strongest predictors of overall survival in the multivariable model (HR 4.11, CI 95%: 1.43-11.76, p = 0.009) after PSM. We further investigated prognostic factors affecting prognosis in AFPP-CRC and found that the presence of liver metastasis was the only independent prognostic factor (HR 4.95, CI 95%: 1.48-16.48, p = 0.009). AFP expression was significantly positively correlated with HGF and c-Met expression. Transwell invasion assay revealed significantly increased cell motility with AFP overexpression. Conclusion: AFP-positivity is a significant negative predictor of overall survival in patients with colorectal cancer, which may be mediated by HGF/c-Met signaling pathway.

Abstract Background Pulmonary sarcomatoid carcinoma is characterized by poor survival rates compared with other non-small cell lung cancer. Prognostic nutritional index has significant prognostic value in many malignant tumors. We conducted this retrospective study to investigate the role of prognostic nutritional index in patients with pulmonary sarcomatoid carcinoma and to determine prognostic factors. Methods Of 8176 patients with resected lung cancer in a single high-volume institution between 2008 and 2015, 91 patients with pathologically diagnosed sarcomatoid carcinoma were included in our study and evaluated. Kaplan–Meier analysis and Cox regression analysis were conducted to analyze clinicopathologic data. Subgroup analysis of overall survival (OS) and recurrence-free survival (RFS) among pulmonary sarcomatoid carcinoma patients were also conducted. Results Univariable analysis showed that tumor size (P = 0.018 in OS), and P = 0.021 in RFS), tumor stage(P < 0.001 in OS, and P = 0.002 in RFS), nodal metastasis (P < 0.001 in OS, and P < 0.001 in RFS), pathological stage (P < 0.001 in OS, and P < 0.001 in RFS), treatment modality (P = 0.032 in OS, and P = 0.059 in RFS) and PNI (P < 0.001 in OS, and P < 0.001 in RFS), were significant factors of both OS and RFS. In multivariable analysis, for OS, the pathological stage (Hazard ratio (HR) 1.432; 95% confidence interval (95% CI) 1.210–1.695; P < 0.001) and PNI (HR 0.812; 95% CI 0.761–0.865; P < 0.001) were independent prognostic factors. And for RFS, We found PNI as an independent prognostic factor (HR 0.792; 95% CI 0.739–0.848; P < 0.001), and the pathological stage (HR 1.373; 95% CI 1.160–1.625; P < 0.001). In the subgroup of patients with PNI ≥ 49.4, univariable analysis showed treatment modality was a significant factor of overall survival (P = 0.001); multivariable analysis showed patients received postoperative chemotherapy (HR 0.288; 95% CI 0.095–0.874; P = 0.028) or postoperative chemotherapy with targeted therapy (HR 0.148; 95% CI 0.030–0.726; P = 0.019) has better overall survival rates. Conclusion The PNI and the pathological TNM stage are independent prognostic factors for pulmonary sarcomatoid carcinoma. PNI is an important indicator for the selection of postoperative adjuvant therapy. Patients with PNI ≥ 49.4 may benefit from postoperative chemotherapy and targeted therapy. We still need further prospective studies to confirm these results.

Time To First Treatment

Purpose The clinical course for patients with chronic lymphocytic leukemia (CLL) is diverse; some patients have indolent disease, never needing treatment, whereas others have aggressive disease requiring early treatment. We continue to use criteria for active disease to initiate therapy. Multivariable analysis was performed to identify prognostic factors independently associated with time to first treatment for patients with CLL. Patients and Methods Traditional laboratory, clinical prognostic, and newer prognostic factors such as fluorescent in situ hybridization (FISH), IGHV mutation status, and ZAP-70 expression evaluated at first patient visit to MD Anderson Cancer Center were correlated by multivariable analysis with time to first treatment. This multivariable model was used to develop a nomogram—a weighted tool to calculate 2- and 4-year probability of treatment and estimate median time to first treatment. Results There were 930 previously untreated patients who had traditional and new prognostic factors evaluated; they did not have active CLL requiring initiation of treatment within 3 months of first visit and were observed for time to first treatment. The following were independently associated with shorter time to first treatment: three involved lymph node sites, increased size of cervical lymph nodes, presence of 17p deletion or 11q deletion by FISH, increased serum lactate dehydrogenase, and unmutated IGHV mutation status. Conclusion We developed a multivariable model that incorporates traditional and newer prognostic factors to identify patients at high risk for progression to treatment. This model may be useful to identify patients for early interventional trials.

Abstract Background: It is well established that antiretroviral therapy (ART) is beneficial in reducing the mortality among patients with human immunodeficiency virus (HIV). In Malaysia, there is lack of study and information regarding the overall survival rates and prognostic factors for survival in HIV-infected adults treated with ART. Therefore, this study aimed to assess and compare the survival rates as well as to identify the prognostic factors for survival among HIV adults in Malaysia.Methods: A retrospective cohort study was conducted by reviewing the medical records of HIV patients who started ART between year 2007 and 2016 at a tertiary referral hospital in Malaysia. ART-naive adults aged 15 years and above were included and those who were transferred out were excluded. After applying inclusion and exclusion criteria, there were 339 cases eligible in this study. Systematic sampling method was applied. Kaplan Meier survival curve and log-rank test were used to compare the overall survival rates. Cox proportional hazards regression was applied to determine the prognostic factors for survival.Results: The estimated overall survival rates were 95.9%, 93.8%, 90.4%, 84.9%, and 72.8% at 6 months, 1 year, 3 years, 5 years and 10 years, respectively. The overall survival rates were significantly different according to age group (p<0.001), employment status (p<0.001), transmission mode (p=0.003), and history of illicit drug use (p=0.017), baseline CD4 cell count (p<0.001), baseline haemoglobin level (p<0.001), tuberculosis co-infection (p<0.001), hepatitis co-infection (p=0.008), first NRTI (p<0.001) and history of defaults (p=0.021). Based on multiple Cox regression, patients who were anaemic had 3.76 times (95% CI: 1.97, 7.18; p<0.001) higher hazard of death than their non-anaemic counterparts. The hazard risk was 2.09 times (95% CI: 1.10, 3.96; p=0.024) higher among HIV patients co-infected with tuberculosis compared to those who were not. Conclusion: Overall survival rates were higher than low-income countries but lower than in high-income countries, and comparable with middle-income countries. Low baseline haemoglobin level and tuberculosis co-infection were strong prognostic factors for HIV survival

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) >180U/L, chemotherapy cycles<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: Metastatic adrenocortical carcinomas (MAC) have a poor prognosis. Advanced adrenocortical carcinoma often metastasizes to lung and liver. Prognostic factors of MAC have been rarely reported. This study aims to identify the association between specific metastasis and overall survival (OS) in MAC and determine the survival predictors for MAC patients.Methods: MAC patients' data was obtained from Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2016. Survival differences were analyzed by Kaplan–Meier analysis and log-rank tests. Cox proportional hazard model was used to identify the prognostic factors associated with overall survival.Results: A total of 152 MAC patients were selected, among whom 77 patients (50.7%) were diagnosed with one metastatic site, 75 (49.3%) diagnosed with more than one distant metastasis. For the whole MAC cohort, multivariable analysis showed that year of diagnosis between 2013 and 2016, without liver metastasis, surgery and chemotherapy were significantly favorable predictors of OS. For patients with one metastatic site, lung metastases had a better survival outcome than liver metastases(p=0.037). Besides, compared with patients who didn’t received surgery, patients underwent surgery were correlated with longer OS (p=0.004). For patients with more than one site of distant metastases, married status, surgery, and chemotherapy predicted a better OS. Radiotherapy did not improve overall survival outcomes in the three cohort.Conclusion: Liver metastasis has a poor prognosis. Year of diagnosis, metastatic sites, surgery and chemotherapy were significant prognostic factors for OS in MAC patients. For patients with single metastasis, surgery was a favorable prognostic factor, while married patients, surgery and chemotherapy predicted a better survival outcome in patients with more than one metastasis. Based on the collective findings, surgery can be regarded as the preferred treatment option for all MAC patients. Besides, chemotherapy is also a good choice for patients with multiple metastases.

Abstract Background: Osteosarcoma is the most common primary malignant bone tumor. The current study was conducted to describe the general condition of patients with primary osteosarcoma in a single cancer center in Tianjin, China and to investigate the associated factors in osteosarcoma patients with lung metastasis. Methods: From February 2009 to October 2020, patients from Tianjin Medical University Cancer Institute and Hospital, China were retrospectively analyzed. The Kaplan–Meier method was used to evaluate the overall survival of osteosarcoma patients. Prognostic factors of patients with osteosarcoma were identified by the Cox proportional hazard regression analysis. Risk factor of lung metastasis in osteosarcoma were investigated by the logistic regression model. Results: A total of 203 patients were involved and 150 patients were successfully followed up for survival status. The 5-year survival rate of osteo-sarcoma patients was 70.0%. Surgery, bone and lung metastasis were the significant prognostic factors in multivariable Cox regression analysis. Twenty-one (10.3%) patients showed lung metastasis at the diagnosis of osteosarcoma and 67 (33%) lung metastases during the later course. T3 stage (OR=11.415, 95%CI 1.362-95.677, P=0.025) and synchronous bone metastasis (OR=6.437, 95%CI 1.69-24.51, P=0.006) were risk factors of synchronous lung metastasis occurrence. Good necrosis (≥90%, OR=0.097, 95%CI 0.028-0.332, P=0.000) and elevated Ki-67 (≥50%, OR=4.529, 95%CI 1.241-16.524, P=0.022) were proved to be significantly associated with metachronous lung metastasis occurrence. Conclusion: The overall survival, prognostic factors and risk factors for lung metastasis in this single center provided insight about osteosarcoma management.

ObjectiveTo analyze the prognostic factors and treatment outcomes in endometrial cancer patients with paraaortic lymph node metastasis.MethodsData from four centers were collected retrospectively for 92 patients with endometrial cancer treated with combined radiotherapy and chemotherapy or adjuvant radiotherapy alone postoperatively, delivered by either the sandwich or sequential method. Prognostic factors affecting overall survival and progression-free survival were analyzed.ResultsThe 5-year overall survival and progression-free survival rates were 35 % and 33 %, respectively, after a median follow-up time of 33 months. The 5-year overall survival and progression-free survival rates were significantly higher in patients receiving radiotherapy and chemotherapy postoperatively compared with patients treated with adjuvant radiotherapy alone (P < 0.001 and P < 0.001, respectively). In a subgroup analysis of patients treated with adjuvant combined chemotherapy and radiotherapy, the 5-year overall survival and progression-free survival rates were significantly higher in patients receiving chemotherapy and radiotherapy via the sandwich method compared with patients treated with sequential chemotherapy and radiotherapy (P = 0.02 and P = 0.03, respectively). In the univariate analysis, in addition to treatment strategy, pathology, depth of myometrial invasion, and tumor grade were significant prognostic factors for both overall survival and progression-free survival. In the multivariate analysis, grade III disease, myometrial invasion greater than or equal to 50%, and adjuvant radiotherapy alone were negative predictors for both overall survival and progression-free survival.ConclusionWe demonstrated that adjuvant combined treatment including radiotherapyand chemotherapy significantly increases overall survival and progression-free survival rates compared with postoperative pelvic and paraaortic radiotherapy.

ObjectiveTo evaluate the role of omentectomy and lymphadenectomy in the treatment of clinically apparent early-stage malignant ovarian germ cell tumors.MethodsWe retrospectively reviewed 245 patients with malignant ovarian germ cell tumors (yolk sac tumor, dysgerminoma, and immature teratoma) and with clinically early-stage disease, who were treated at Sun Yat-sen University Cancer Center between January 1, 1970 and December 31, 2017. The survival of patients who underwent either omentectomy or lymphadenectomy, or both (omentectomy/lymphadenectomy group) was compared with that of patients who did not undergo omentectomy or lymphadenectomy (non-omentectomy/lymphadenectomy group).ResultsSixty patients were diagnosed with yolk sac tumor, 74 with dysgerminoma, and 111 with immature teratoma. Of these 245 patients, 216 patients had stage I disease, 28 patients had stage II, and 1 patient had stage IIIA. There were 190 patients who underwent omentectomy and/or lymphadenectomy and 55 patients in the non-omentectomy/lymphadenectomy group, respectively. In the omentectomy/lymphadenectomy group, 112 patients underwent both omentectomy and lymphadenectomy, 71 underwent omentectomy only, and 7 underwent lymphadenectomy only. Two hundred and fourteen of 245 patients (87.3%) received post-operative chemotherapy. Median follow-up was 73 months (range 1–388). The 10-year overall survival rates in the omentectomy/lymphadenectomy group and non-omentectomy/lymphadenectomy groups were 96.8% and 100%, respectively (p=0.340). Multivariate analysis evaluating all potential prognostic factors showed that omentectomy and lymphadenectomy are not prognostic factors for survival.ConclusionsOmentectomy and lymphadenectomy do not appear to improve survival and may be omitted in patients with clinically apparent early-stage malignant ovarian germ cell tumors.

PURPOSE To evaluate the benefit of anthracycline-based chemotherapy, identify prognostic factors, and determine the value of the International Prognostic Factors Index for patients with follicular large-cell (FLC) lymphoma. PATIENTS AND METHODS This retrospective study includes 96 patients with FLC lymphoma treated at Stanford University Medical Center between 1969 and 1991. Fifty-five patients received doxorubicin plus cyclophosphamide-containing chemotherapy regimens, 21 patients received other chemotherapy regimens, 15 patients received radiotherapy only, and five patients received no initial therapy. Thirty-four patients had stage I or II disease and 62 patients had stage III or IV disease. RESULTS With a median follow-up duration of 5.2 years (range, 1 to 18), the actuarial 5- and 10-year overall survival rates were 75% and 54%, with actuarial 5- and 10-year freedom from progression (FFP) rates of 53% and 42%, respectively. Patients treated with chemotherapy regimens that contained both doxorubicin and cyclophosphamide had a superior actuarial 10-year FFP rate (55% v 25%, P = .06) and overall survival rate (65% v 42%, P = .04) compared with patients treated with other chemotherapy regimens. Only one patient treated with doxorubicin plus cyclophosphamide relapsed after 3 years. In the multivariate analysis, discordant lymphoma and treatment with chemotherapy regimens not containing both cyclophosphamide and doxorubicin predicted for worse FFP and overall survival rates. In addition, poor performance status and increasing areas of diffuse histology predicted for a worse survival, while anemia and male sex predicted for a worse FFP. The age-specific International Index was useful in predicting outcome; however, few patients with FLC lymphoma had high-risk features. CONCLUSION The plateau in FFP implies that patients with FLC lymphoma enjoy sustained remissions after standard anthracycline-based chemotherapy. FLC lymphoma should continue to be approached as an intermediate-grade lymphoma with curative intent.
