Adenosquamous Cancer

ObjectivesThere are few reports about the survival rate of patients with pancreatic adenosquamous cancer (PASC). This study evaluated and analyzed prognostic factors of patients with resectable pancreatic adenosquamous cancer (rPASC), which might fulfill the blank in the research of PASC.MethodsIn this study, we identified and analyzed 55 patients who were diagnosed with rPASC from January 2013 to May 2019 at the Pancreatic Disease Center of the Shanghai Ruijin Hospital affiliated with Shanghai Jiaotong University School of Medicine. Age, sex, BMI, tumor position, and other important demographic data were collected and analyzed. The follow-up was updated by December 31th, 2019 with a median follow-up of nine months.ResultsAmong the 55 patients, 23 (41.8%) patients were female, and the mean age was 62.0 ± 10.3 years. The median overall survival (OS) time was 10 ± 2.1 months, and the median disease-free survival (DFS) time was 4 ± 0.9 months. The 1-year, 3-year, and 5-year survival rates were 40.9, 17.5, and 11.6%, respectively. The multivariate analysis showed that normal serum level of Ca199 (HR = 0.464, 95% CI = 0.222–0.970, P = 0.041) and Ca125 (HR = 0.441, 95% CI = 0.233–0.835, P = 0.012) were independent favorable prognostic factors.ConclusionPatients with rPASC had poor survival. The 5-year survival rate was only 11.6%. Normal serum levels of Ca199 and Ca125 were independent favorable prognostic factors that predicted prognosis.

Background/Purpose: Gastric gastrointestinal stromal tumors (GISTs) have a highly variable clinical course, and recurrent disease sometimes develops despite curative surgery. This study was undertaken to investigate the surgical role in treating gastric GISTs and evaluate the clinicopathological features of a large series of patients who underwent curative resection for gastric GISTs to clarify which features were independent prognostic factors. Methods: The clinicopathological data of 406 patients with gastric GISTs who underwent curative resection at 4 university hospitals in Daegu, South Korea, from March 1998 to March 2012 were reviewed. All cases were confirmed as gastric GISTs by immunohistochemical staining, in which CD117 or CD34 was positive. Clinical follow-up was performed periodically, and disease-free survival rates were retrospectively investigated using the medical records. Results: The mean follow-up period was 42.9 months (range: 2-166). There were 11 recurrent patients (2.7%). Due to the small number of recurrences, age, sex and location were controlled using propensity score matching before performing any statistical analysis. Tumor size, mitotic count, NIH classification, and cellularity were judged to be independent prognostic factors for recurrence by univariate analysis. In a multivariate analysis, tumor size and mitotic count were significantly and independently related to recurrence, and tumor size was determined to be the most important prognostic factor for recurrence after curative resection (hazard ratio: 1.204; p < 0.01). Conclusions: The results of this multicenter study demonstrate that disease-free survival rates are good. Tumor size was disclosed as the most important factor for recurrence in gastric GIST patients who underwent radical resection.

8520 Background: The EVAN study of E vs NP in stage III EGFR+ NSCLC has met its primary endpoint and been previously published: 2-year disease-free survival was 81.4% (95% CI, 69.6–93.1) in E group vs 44.6% (95% CI, 26.9-62.4) in NP group (HR, 1.823; 95% CI, 1.194–2.784; P=0.0054). We report 5-year OS and exploratory results from EVAN with a further 43 month follow up (cutoff date: Jan 6, 2021). Methods: Patients with stage IIIA EGFR+ NSCLC were randomized assigned (1:1) into either E arm (n=51, 150mg/day) or NP arm (n=51, vinorelbine 25mg/m2 on day 1, 8 and cisplatin 75mg/m2 on day 1 of a 21-day cycle). In order to explore the relationship between patient benefits and co-occurring variants, 47 patients received whole exome sequencing (WES) analysis (E, n=24; NP, n=23). Results: Median follow-up time was 54.8 months for E and 63.9 months for NP. E improved OS and 5-year survival rate compared with NP in ITT population. The median OS was 84.2m (95% CI, 78.1,-) with E vs 61.1m (95% CI, 39.6-82.1) with NP (HR, 0.318; 95% CI, 0.151-0.670). The 5-year survival rates were 84.8% (95%CI, 72.0-97.6) and 51.1% (95% CI, 34.7-67.5), respectively. In the WES analysis, we found that the most frequent genes with co-occurring variants at baseline were TP53, MUC16, FAM104B, KMT5A and DNAH9, and additional EGFR variants, each with similar prevalence regardless of EGFR-activating mutation subgroup. Moreover, in the erlotinib-treated patients, the SNP mutation of UBXN11 was associated with significantly worse DFS (P=0.0111). Conclusions: This is the first randomized study of EGFR-TKI to demonstrate a clinically meaningful improvement in OS vs chemotherapy in stage III EGFR+ NSCLC (5-year survival rate 84.8% in E vs 51.1% in NP). The co-occurring variants at baseline may be associated with reduced DFS. Further studies are required to confirm our results (EVAN, NCT01683175). Clinical trial information: NCT01683175.

One hundred sixty-three patients with advanced non-Hodgkin's lymphoma including adult T cell leukemia/lymphoma (ATL) were treated from 1981 to 1983 with VEPA (vincristine, cyclophosphamide, prednisolone, and doxorubicin) or VEPA-M (VEPA plus methotrexate) in randomized fashion after stratification by surface marker. The complete response (CR) rate and the 4-year survival rate of patients treated with VEPA-M was 62.2% and 36.9%, respectively, while for those treated with VEPA the rates were 51.9% and 26.6, respectively. The difference was not statistically significant, but pretreatment characteristics predictive for response and survival were interesting. Three factors, leukemic change, poor performance status (PS), and T cell marker, were negatively associated with both CR and survival rates, and high-grade pathology was adversely associated with survival rate in a multivariate analysis. These prognostic factors are somewhat different from those in Western lymphomas. This may be reflection of major differences in patients' characteristics between Japanese and Western lymphomas: in this study, there was a high incidence of T cell lymphoma/leukemia (50%) including ATL (33%), leukemic manifestation (34%), poor PS (34%), and a low incidence of follicular lymphoma (9%). The statistically significant three factors for both CR and survival rates were used to construct a model containing eight categories of patients at increasing risk for poor response and shortened survival. These categories were divided into four groups, with respective CR and 4-year survival rates of 91% and 73%, 67% and 35%, 27% and 7%, and 10% and 5%. Ninety-three patients in whom CR was induced by VEPA or VEPA-M therapy were evaluated for prognostic factors predictive for disease-free survival. A shorter period (less than 28 days) required to achieve CR, a clinical diagnosis of ATL, and a lower hemoglobin level were found to affect disease-free survival adversely. These results have important implications for both the design of prospective randomized therapeutic trials and the determination of optimal therapy for individual patients.

ABSTRACT OBJECTIVE To determine the patterns of relapse and the prognostic factors for adult medulloblastomas treated in the magnetic resonance imaging era. METHODS Between 1986 and 1996, 32 adult patients (age, ≥16 yr) with medulloblastomas confined to the craniospinal axis were treated in our institutions. Twenty cases involved classic histological features and 12 involved the desmoplastic variant. The Chang staging distribution was as follows: T1, 2; T2, 17; T3, 10; T4, 3; M0, 24; M1, 1; M2, 4; M3, 3. Brainstem invasion was present in nine patients. Lesions were midline in 13 cases and lateral in 19. Resection was complete in 17 cases, subtotal in 6, and partial in 5, with biopsy only in 4 cases. All patients received postoperative radiotherapy, with median doses of 36 Gy to the entire craniospinal axis and 55 Gy to the posterior fossa. Twenty-four patients received chemotherapy (20 before radiotherapy, 3 after radiotherapy, and 1 before and after radiotherapy). RESULTS With a median follow-up period of 5.4 years, 17 patients experienced recurrences. At 5 and 8 years, overall survival rates were 83 and 45% and disease-free survival rates were 57 and 40%, respectively. The 5- and 8-year posterior fossa control rates were 67 and 59%, respectively. Twenty-nine percent of all relapses occurred more than 5 years after treatment. The posterior fossa was the most common site of relapses. In univariate analyses, factors adversely affecting posterior fossa control were less than complete resection (P &lt; 0.001), the presence of brainstem invasion (P = 0.02), and the use of chemotherapy (P = 0.03). The overall radiotherapy duration was marginally significant in predicting posterior fossa control, with 5-year posterior fossa control rates of 81 and 49% for durations of less than 48 days and 48 days or more, respectively (P = 0.06). In a multivariate analysis, complete resection was predictive of improved posterior fossa control (P = 0.02) and disease-free survival (P = 0.02) rates. Of the eight low-risk patients who received radiotherapy alone, three experienced recurrences in the bone as the only site of relapse. CONCLUSION Late relapse is common among adult patients with medulloblastomas, and long-term follow-up monitoring is important. Because of the high risk of systemic failure among the low-risk patients treated with radiotherapy alone, the role of chemotherapy for this group of patients needs to be further investigated. Complete resection, the absence of brainstem invasion, and an overall radiotherapy duration of less than 48 days are important prognostic factors.

PURPOSE: To determine the toxicity and recommended phase II doses of the combination of fludarabine plus cyclophosphamide in chemotherapy-naive patients with low-grade lymphoma. PATIENTS AND METHODS: Previously untreated patients with low-grade lymphoma were entered onto dosing cohorts of four patients each. The cyclophosphamide dose, given on day 1, was increased from 600 to 1,000 mg/m2. Fludarabine 20 mg/m2 was administered on days 1 through 5. The first eight patients were treated every 21 days; later patients were treated every 28 days. Prophylactic antibiotics were required. RESULTS: Prolonged cytopenia and pulmonary toxicity each occurred in three of eight patients treated every 3 weeks. The 19 patients treated every 28 days, who were given granulocyte colony-stimulating factor as indicated, did not have undue nonhematologic toxicity. Dose-limiting toxicity was hematologic. At the recommended phase II/III dose (cyclophosphamide 1,000 mg/m2), grade 4 neutropenia was observed in 17% of all cycles and 31% of first cycles. Grade 3 or 4 thrombocytopenia was seen in only 1% of all cycles. The median number of cycles per patient was six (range, two to 11) for all patients enrolled. The response rate was 100% of 27 patients entered; 89% achieved a complete and 11% a partial response. Nineteen of 22 patients with bone marrow involvement had clearing of the marrow. Median duration of follow-up was more than 5 years; median overall and disease-free survival times have not been reached. Kaplan-Meier estimated 5-year overall survival and disease-free survival rates were 66% and 53%, respectively. CONCLUSION: The recommended dosing for this combination in patients with previously untreated low-grade lymphoma is cyclophosphamide 1,000 mg/m2 day 1 and fludarabine 20 mg/m2 days 1 through 5. The regimen has a high level of activity, with prolonged complete remissions providing 5-year overall and disease-free survival rates as high as those reported for other therapeutic approaches in untreated patients.

This retrospective study evaluated the survival rate of short, sandblasted acid-etched surfaced implants with 6 and 8 mm lengths with at least 120 days of follow-up. Data concerning patient, implant and surgery characteristics were retrieved from clinical records. Sandblasted and acid-etched (SLA)-surfaced tissue-level 6 mm (TL6) or 8 mm (TL8) implants or bone-level tapered 8 mm (BLT8) implants were used. Absolute and relative frequency distributions were calculated for qualitative variables and mean values and standard deviations for quantitative variables. A Cox regression model was performed to verify whether type, length and/or width influence the implant survival. The cumulative implant survival rate was assessed by time-to-event analyses (Kaplan–Meier estimator). In all, 513 patients with a mean age of 58.00 ± 12.44 years received 1008 dental implants with a mean follow-up of 21.57 ± 10.77 months. Most implants (78.17%) presented a 4.1 mm diameter, and the most frequent indication was a partially edentulous arch (44.15%). The most frequent locations were the posterior mandible (53.97%) and the posterior maxilla (31.55%). No significant differences were found in survival rates between groups of type, length and width of implant with the cumulative rate being 97.7% ± 0.5%. Within the limitations of this study, the evaluated short implants are a predictable option with high survival rates during the follow-up without statistical differences between the appraised types, lengths and widths.

Introduction: This study aims to assess the correlation of the age-adjusted Charlson comorbidity index (ACCI) with 5-year mortality in a surgically treated hip fracture population. Materials and Methods: A retrospective analysis was performed on 1057 patients aged 60 years and above who underwent surgery for hip fracture with a minimum of 5-year follow-up (92.2% 5-year follow-up rate) in a tertiary hospital. Manual review of patients’ electronic hospital records was performed to record demographic data, comorbidities, and length of stay. Mortality data were extracted from the hospital’s electronic medical records and corroborated with the National Electronic Health Record. Results: Of the 1057 patients, 283 (26.8%) were male. The majority of patients were 80 years of age and above (42.5%), with the oldest patient operated on age 102 with a mean age of 77.8 (8.6) years. Four hundred eighteen (39.5%) patients sustained extracapsular intertrochanteric fractures. The mean follow-up duration was 8 years and 3 days with an overall survivorship of 37.2%. A multiple regression model constructed with ACCI, age, gender, and fracture pattern demonstrated satisfactory predictive ability with a concordance statistic of 0.68. Patients with a higher ACCI category (≥6) had an increased 5-year mortality rate (41.8%) with an odds ratio of 13.6 (6.7-31.8, P < .001) compared to those with an ACCI category of 3 and below (89.3%). Discussion: The study demonstrates that ACCI correlated with 5-year mortality after surgical treatment of hip fracture. This information is pertinent in the counseling of patients with regard to their midterm survival following hip fracture surgery and may inform policy makers of the varied midterm survival rates in patients with differing ACCI scores and educate the allocation of health-care resources. Conclusion: The ACCI correlates with 5-year mortality after surgical treatment of hip fracture.

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.

PurposePrimary effusion lymphoma (PEL) is a rare high-grade B-cell non-Hodgkin's lymphoma associated with Kaposi sarcoma–associated herpesvirus/human herpesvirus 8 (KSHV/HHV-8) infection, and is mostly observed in the course of HIV infection. The prognosis is poor, with reported median survival time shorter than 6 months. To date, no prognostic factor has been identified in this subset of lymphoma.Patients and MethodsWe describe here a large series of HIV-infected patients with PEL, including 28 cases diagnosed in six centers during an 11-year time period. Prognosis analysis was performed using a Cox proportional hazard regression model. Statistically significant covariates were further analyzed in a forward, stepwise multivariate model.ResultsAfter a median follow-up of 3.8 years (range, 10 months to 10.8 years), nine patients (32%) were still alive, and eight of them remained progression free. The median survival was 6.2 months, and the 1-year overall survival rate was 39.3%. Fourteen patients (50%) achieved complete remission, with a 1-year disease-free survival rate at 78.6%. In a multivariate analysis, only a performance status more than 2 (hazard ratio, 5.84; 95% CI, 1.76 to 19.33) and the absence of highly active antiretroviral therapy (HAART) before PEL diagnosis (hazard ratio, 3.26; 95% CI, 1.14 to 9.34) were found to be independent predictors for shorter survival.ConclusionBased on a retrospective series of 28 patients, two prognostic factors were identified as being independently associated with impaired clinical outcome in HIV-related PEL—(1) a poor performance status and (2) the absence of HAART before PEL diagnosis.
