Introduction. Chondrosarcomas are malignant bone tumors that are characterized by the production of chondroid tissue. Since radiation therapy and chemotherapy have limited effect on chondrosarcoma, treatment of most patients depends on surgical resection. We conducted this study to identify independent predictive factors and survival characteristics for conventional central chondrosarcoma and dedifferentiated central chondrosarcoma.Methods. A systematic literature review was performed in September 2014 using the Pubmed, Embase, and Cochrane databases. Subsequent to a beforehand-composed selection procedure we included 13 studies, comprising a total of 1114 patients.Results. The prognosis of central chondrosarcoma is generally good for the histologically low-grade tumors. Prognosis for the high-grade chondrosarcoma and the dedifferentiated chondrosarcoma is poor with lower survival rates. Poor prognostic factors in conventional chondrosarcoma for overall survival are high-grade tumors and axial/pelvic tumor location. In dedifferentiated chondrosarcoma the percentage of dedifferentiated component has significant influence on disease-free survival.Conclusion. Despite the fact that there are multiple prognostic factors identified, as shown in this study, there is a need for prospective and comparative studies. The resulting knowledge about prognostic factors and survival can give direction in the development of better therapies. This could eventually lead to an evidence-based foundation for treating chondrosarcoma patients.

Abstract Background: To evaluate the influence of treatment modalities and prognostic factors on the survival of patients with low-grade endometrial stromal sarcoma (LGESS). Methods: One hundred and thirty-five LGESS patients in Fudan University Shanghai Cancer Center from January 2006 to December 2018 were retrospectively reviewed. Results: Two patients received fertility-sparing surgery while 133 patients received hysterectomy. The median follow-up duration was 52 months (3–342 months). One hundred and nine (80.7%) patients received ovariectomy, 73 (54.1%) patients had lymphadenectomy, 83 (61.5%) patients received adjuvant therapy. The 5-year and 10-year disease free survival rates were 72.0% and 61.0%, respectively. The 5-year and 10-year overall survival rates were 88.0% and 79.8%, respectively. Surgery for recurrence was associated with improved overall survival although the complication rate was about 27.6%. Multivariate analysis showed that lymphovascular invasion was associated with disease free survival (hazard ratio, 0.473; 95 % confidence interval, 0.235–0.952; p=0.036) and menopausal status was related to overall survival (hazard ratio, 5.561; 95 % confidence interval, 1.400–22.084; p=0.015). Conclusions: There was no effect of lymphadenectomy, ovariectomy, or adjuvant therapy on patients’ recurrence and survival. Hysterectomy may be proposed as the standard treatment for LGESS. Surgery for replase was an acceptable method to improve overall survival. Lymphovascular invasion was a significant independent factor for disease free survival. Postmenopause was the poor prognostic factor for overall survival.

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.

Objective and design A clinicopathological score has been proposed by Trouillas et al. to predict the evolution of pituitary adenomas. Aim of our study was to perform an independent external validation of this score and identify other potential predictor of post-surgical outcome. Methods The study sample included 566 patients with pituitary adenomas, specifically 253 FSH/LH-secreting, 147 GH-secreting, 85 PRL-secreting, 72 ACTH-secreting and 9 TSH-secreting tumours with at least 3-year post-surgical follow-up. Results In 437 cases, pituitary adenomas were non-invasive, with low (grade 1a: 378 cases) or high (grade 1b: 59 cases) proliferative activity. In 129 cases, tumours were invasive, with low (grade 2a: 87 cases) or high (grade 2b: 42 cases) proliferative activity. During the follow-up (mean: 5.8 years), 60 patients developed disease recurrence or progression, with a total of 130 patients with pituitary disease at last follow-up. Univariate analysis demonstrated a significantly higher risk of disease persistence and recurrence/progression in patients with PRL-, ACTH- and FSH/LH-secreting tumours as compared to those with somatotroph tumours, and in those with high proliferative activity (grade 1b and 2b) or >1 cm diameter. Multivariate analysis confirmed tumour type and grade to be independent predictors of disease-free-survival. Tumour invasion, Ki-67 and tumour type were the only independent prognostic factors of disease-free survival. Conclusions Our data confirmed the validity of Trouillas’ score, being tumour type and grade independent predictors of disease evolution. Therefore, we recommend to always consider both features, together with tumour histological subtype, in the clinical setting to early identify patients at higher risk of recurrence.

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.

The impact of tumor location on patient survival in pancreatic ductal adenocarcinoma (PDAC) remains controversial. This study investigated the association between primary tumor location and survival rates for resectable PDAC. Additionally, we assessed if this association remains consistent across categories of the Tumor-Node-Metastasis staging system. We analyzed 2471 patients who underwent surgical resection between 2000 and 2018 at a single center. Subgroup analysis was performed according to the Tumor-Node-Metastasis staging system. Among the group, 67.9% (1677 patients) had pancreatic head cancer (PHC) and 32.1% (794 patients) had pancreatic body/tail cancer (PBTC). Patients with PHC had worse overall survival and worse disease-free survival than those with PBTC. Patients with PHC had worse survival in stage IB and stage IIB than those with PBTC. No significant difference was observed for stages IA, IIA, and III. Multivariate analysis showed that elevated CA 19-9, mGPS, a longer hospital stay, complication, accompanying vein resection, larger tumor size, worse differentiation, higher TNM stage (stage IIB, III, IV), presence of LVI, and positive resection margin were risk factors for poor survival after resection. In resectable PDAC, patients with PHC had worse overall and disease-free survival than those with PBTC. However, tumor location was not an independent prognostic factor for PDAC.

AbstractThis study investigated the correlation between pancreatic fibrosis (PF) and development of pancreoprivic diabetes after pancreaticoduodenectomy (PD). Ninety-five patients who underwent PD at Gangnam Severance Hospital between 2014 and 2017 were enrolled. PF grade was evaluated with alpha-smooth muscle actin (SMA) and Masson’s trichrome (TRC) staining. New-onset pancreoprivic diabetes and recurrence of disease were evaluated using fasting blood glucose measurement and radiography taken at 3-month intervals. Sixty-one patients did not have preoperative diabetes, however, 40 (65.6%) patients developed pancreoprivic diabetes after PD. High-grade PF was more common in the diabetes group than in the normal group (SMA, 42.5% vs. 28.6%, P = 0.747; TRC, 47.5% vs. 28.6%, P = 0.361). The 1-year cumulative incidence of hyperglycemia/pancreoprivic diabetes was higher with high-grade PF than low-grade PF (SMA, 94.4% vs. 73.0%, P = 0.027; TRC, 89.3% vs. 75.0%, P = 0.074). The SMA-TRC combined high-grade group had a higher proportion of primary pancreatic disease than the combined low-grade group (90.0% vs. 37.5%, P = 0.001). The 5-year disease-free survival of patients with pancreatic cancer was worse with high-grade PF than low-grade PF (SMA, 24.5% vs. 66.3%, P = 0.026; TRC, 23.6% vs. 58.4%, P = 0.047). In conclusion, patients with severe PF are more likely to develop pancreoprivic diabetes after PD and have worse disease-free survival.

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.

AbstractBackgroundto investigate endometrial carcinoma prognostic value of some histopathological and immunohistochemical factors, fairly easily accessible in every routinely pathology lab set.Methodswe considered patients affected by endometrial carcinoma with available clinical and radiological follow-up data after radical hysterectomy (S. Martino Polyclinic Hospital, Genoa, Italy, period 1/1/2013 - 1/7/2016). We analyzed the following histopathological items: histotype, stage (FIGO), type of infiltration (infiltrative/espansive), desmoplasia, intratumoral necrosis, tumor infiltrating lymphocytes and lymph vascular spaces invasion. Moreover, each case has been investigated with a panel of immunohistochemistry including estrogen receptor α, progesteron receptor, Ki67, p53, β-catenin, e-cadherin, bcl-2 and cyclin D1. Primary endpoints were disease free survival and overall survival.Resultsout of 99 cases eligible for our purpose, we found 69 low-grade endometrioid, 8 high-grade endometrioid and 22 other high-grade endometrial carcinomas. Disease free survival multivariate analysis showed a strong significant correlation between poor prognosis and advanced stage (p=0.0042). Advanced stage (p=0.0003) and presence of desmoplasia (p=0.04) resulted significantly correlated to a worse prognosis in overall survival multivariate analysis. In univariate model, the non-endometrioid histotype was significantly correlated with an unfavorable prognosis when compared to the endometriod type. Same for progesteron receptor low expression.Conclusionthe multivariate analysis confirmed the central prognostic role of stage in endometrial carcinoma. Moreover, other immunohistochemical markers in univariate analysis, have confirmed their easily reproducible usefulness, well integrating the recent TGCA molecular classification.

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.
