Object It has been suggested that synchronous brain metastases (that is, those occurring within 2 months of primary cancer diagnosis) are associated with a shorter survival time compared with metachronous lesions (those occurring greater than 2 months after primary cancer diagnosis). In this study the authors used data obtained from the National Cancer Institute's Surveillance, Epidemiology, and End Results Program to determine the incidence of synchronous brain metastases and length of survival of patients in a defined population of southeastern Michigan residents. Methods Data obtained in 2682 patients with synchronous brain metastases treated from 1973 to 1995 were reviewed. Study criteria included patients in whom at least one brain metastasis was diagnosed within 2 months of the diagnosis of primary cancer and those with an unknown primary source. The incidence per 100,000 increased fivefold, from 0.69 in 1973 to 3.83 in 1995. The most frequent site for the primary cancer was the lung (75.4%). The second largest group (10.7%) consisted of patients in whom the primary site was unknown. The median survival length was 3.3 months. There was no significant difference in the median survival in patients with primary lung/bronchus and those with an unknown primary site (3.2 months and 3.4 months, respectively). Conclusions Patients who present with synchronous lesions have a poor prognosis, and the predominant cause of death, in greater than 90% of cases, is related to systemic disease; however, despite poor median survival lengths, certain patients will experience prolonged survival.

IntroductionPatients with cancer of unknown primary (cup) have pathologically confirmed metastatic tumours with unidentifiable primary tumours. Currently, very little is known about the relationship between the treatment of patients with cup and their survival outcomes. Thus, we compared oncologic treatment and survival outcomes for patients in Ontario with cup against those for a cohort of patients with metastatic cancer of known primary site.Methods Using the Ontario Cancer Registry and the Same-Day Surgery and Discharge Abstract databases maintained by the Canadian Institute for Health Information, we identified all Ontario patients diagnosed with metastatic cancer between 1 January 2000 and 31 December 2005. Ontario Health Insurance Plan treatment records were linked to identify codes for surgery, chemotherapy, or therapeutic radiation related to oncology. Multivariable Cox regression models were constructed, adjusting for histology, age, sex, and comorbidities.Results In 45,347 patients (96.3%), the primary tumour site was identifiable, and in 1743 patients (3.7%), cup was diagnosed. Among the main tumour sites, cup ranked as the 6th largest. The mean Charlson score was significantly higher (p < 0.0001) in patients with cup (1.88) than in those with a known primary (1.42). Overall median survival was 1.9 months for patients with cup compared with 11.9 months for all patients with a known-primary cancer. Receipt of treatment was more likely for patients with a known primary site (n = 35,012, 77.2%) than for those with cup (n = 891, 51.1%). Among patients with a known primary site, median survival was significantly higher for treated than for untreated patients (19.0 months vs. 2.2 months, p < 0.0001). Among patients with cup, median survival was also higher for treated than for untreated patients (3.6 months vs. 1.1 months, p < 0.0001).Conclusions In Ontario, patients with cup experience significantly lower survival than do patients with metastatic cancer of a known primary site. Treatment is associated with significantly increased survival both for patients with cup and for those with metastatic cancer of a known primary site.

Abstract Brain metastases comprise the majority of central nervous tumors in adults and confer poorer survival for patients with primary cancer. Systemic disease control is improving with advances in treatment for primary tumors and the complexity of brain metastases management is increasing with multimodality approaches incorporating combinations of surgery, radiotherapy, chemotherapy, targeted therapies, and immunotherapy. Accordingly, the Society for Neuro-Oncology established an annual brain metastases conference to unite colleagues from multiple disciplines with content spanning a range of timely topics relevant to improving our understanding of brain metastases and how they are optimally treated. The inaugural meeting on August 16–17, 2019 was very successful with 163 impactful presentations being delivered to a large multidisciplinary audience on current research advances in the field of neuro-oncology. This review summarizes the major themes of the meeting and highlights the main findings presented.

159 Background: Brain metastases from esophageal carcinoma have historically been rare. With improvements in systemic therapy, patients are living longer and the incidence of brain metastasis (mets) is expected to rise. However, there is no consensus on management. We present our single institution experience with brain mets from esophageal cancer. Methods: We retrospectively identified 49 patients (pts) with brain mets from primary esophageal cancer who were treated at our tertiary referral center between 1998 and 2015. Medical records were reviewed to collect demographic and clinical information. Results: Median age at diagnosis of the primary esophageal cancer was 60 years. 41 pts were male. 39 pts had adenocarcinoma, 4 had squamous cell carcinoma, 4 had poorly differentiated carcinoma, and 1 had neuroendocrine carcinoma. Stage at diagnosis ranged from I-IV. 7pts had synchronous brain mets, defined as occurring within 3 months of diagnosis. The remaining pts were found to have brain mets more than 3 months after diagnosis. 27 pts had a solitary met, 12 had two lesions, and the rest had multiple lesions. For primary treatment, 12 pts had surgery only, 8 had stereotactic radiosurgery (SRS) as a definitive treatment, and the remainder had a combination of surgery, SRS, and whole brain radiation therapy. Median survival following esophageal cancer diagnosis was 24 months (range 3-71), and median survival after the identification of brain mets was 5 months (range 1-52). Using the recursive partitioning score (RPA), 15 pts had class I disease and 28 had class II, and 6 had class III disease. Those with class I or II disease had significantly improved overall survival (p < 0.001). Conclusions: Brain metastases from esophageal cancer are rare with overall poor prognosis. However, some pts can have prolonged survival. In the largest series to date, we found that pts with controlled systemic disease and limited number of brain lesions who had definitive therapy (surgery or SRS) had better outcome. Aggressive treatment may improve outcomes.

Abstract With the development of site-specific cancer therapy, identifying the primary origin allows the oncologist to personalise therapy for patients with the cancer of unknown primaries (CUPs). At present, immunohistochemistry (IHC) screening is the standard method used to postulate the primary site in CUP. In this retrospective study, we evaluated the prognostic benefit of identifying the primary site in CUP. All 84 patients who presented with suspected CUP to the Royal Stoke University Hospital between 2011 and 2012 were included in our study. Forty-eight percent (40/84) of these patients were unable to undergo necessary investigations to identify primary sites because of poor performance status. IHC screening was able to postulate the primary site in 59% (26/44) of the remaining patients with confirmed CUP. Therefore, the primary site was not identified in a significant proportion of patients with CUP. The median survival of confirmed CUP with probable primary site was 2.0 months (95% confidence interval (CI): 1.2 to 2.9 months), whereas the median survival of confirmed CUP with no probable primary site was 4.1 months (95% CI: 1.5 to 9.7 months). This difference in survival time was statistically significant. In addition, using the Cox regression model, we found that patients with confirmed CUP with primary sites had prognostically unfavourable diseases with a shorter median survival, regardless of the age of disease onset, gender, sites of metastases or number of metastases. One approach to improve the survival would be to start systemic therapy at the earliest possible opportunity rather than waiting for all investigation results, such as IHC.

PURPOSE We performed this study to identify prognostic factors in a subgroup of patients with carcinoma of unknown primary site treated with cisplatin combination chemotherapy. PATIENTS AND METHODS Seventy-nine patients with poorly differentiated adenocarcinoma or undifferentiated carcinoma of unknown primary site were treated on two consecutive phase II chemotherapy protocols. The first protocol consisted of treatment with 3-week courses of cisplatin, etoposide, and bleomycin (BEP). In the second protocol, cisplatin was administered weekly combined with oral administration of etoposide (DDP/VP). To identify prognostic factors, univariate and multivariate analyses were conducted. RESULTS In the univariate analysis, performance status, histology, liver or bone metastases, and serum levels of alkaline phosphatase and AST were significant variables to predict survival. In the multivariate analysis, performance status and alkaline phosphatase were the most important prognostic factors. CONCLUSION Good-prognosis patients had a performance score of 0 (World Health Organization [WHO]) and an alkaline phosphatase serum level less than 1.25 times the upper limit of normal (N). These patients had a median survival duration greater than 4 years. Intermediate-prognosis patients were characterized by either a WHO performance status < or = 1 or an alkaline phosphatase level > or = 1.25 N. These patients had a median survival duration of 10 months and a 4-year survival rate of only 15%. The poor-prognosis group had both a WHO performance status > or = 1 and an alkaline phosphatase level > or = 1.25 N. These patients had a median survival duration of only 4 months and none survived beyond 14 months. Treatment strategies for these three groups are discussed. It is suggested that this prognostic model be validated in other patients series.

The combination of 5-fluorouracil (5-FU), doxorubicin, and mitomycin (FAM) is often recommended for empiric management of patients with adenocarcinoma of unknown primary. This recommendation is based on the activity of FAM for adenocarcinomas of specific known sites of origin. A literature search disclosed no reports of the efficacy of FAM in this clinical entity. We report on 45 patients with biopsy-proven adenocarcinoma in whom investigation revealed no primary site and who were treated in a phase II trial with FAM. Of 43 evaluable patients, four achieved a complete tumor response, and nine obtained a partial response for an overall response rate of 30%. The median survival for all patients was greater than 10 months. The median survival for patients whose tumors were unresponsive to FAM was 6 months, and median survival was greater than or equal to 14 months in patients with stable disease or FAM-responsive tumors. A phase III trial comparing no therapy or 5-FU with FAM is warranted. For patients not treated in an investigative setting, FAM compares favorably with reported series using other regimens.

Background and Aims: There is a lack of research on metastatic renal pelvis cell carcinoma in the current literature. In this study, we aimed to detect distant metastatic patterns in renal pelvis cell carcinoma, and illustrated the affection of different metastatic sites, surgery to primary site and chemotherapy on prognosis outcomes in patients with diverse conditions. Methods: We collected data between 2010 and 2015 from the Surveillance, Epidemiology and End Results database. Kaplan–Meier analysis with log-rank test was used for survival comparisons. Multivariate Cox regression model was employed to analyze the effect of distant metastatic sites on overall survival (OS) and cancer-specific survival (CSS). Results: A total of 424 patients were included in the analysis, the median follow-up time was 5 months (interquartile range (IQR): 2-12) and 391 deaths (92.2%) in all patients were recorded. Among them, 192 (45.3%), 153 (36.1%), 137 (32.3%) and 127 (30.0%) patients were diagnosed with lung, bone, liver and brain metastases, respectively, while only 12 (2.8%) patients had brain metastases. The bi-organ, tri-organ and tetra-organ metastatic pattern was found in 135 (31.8%), 32 (7.5%) and 11 (2.6%) patients, respectively. The multivariate Cox analyses showed that distant lymph nodes (DL) metastases was not an independent prognostic factor for both OS and CSS (OS: Hazard ratios (HR) = 1.1, 95% CI = 0.8-1.4, P = 0.622; CSS: HR = 1.0, 95% CI = 0.8-1.3, P = 0.906). Besides, there was no significant difference of survival in patients with T3-T4 stage (OS: HR = 0.8, 95% CI = 0.5–1.2, P = 0.296; CSS: HR = 0.8, 95% CI = 0.5–1.2, P = 0.224), N2-3 stage (OS: HR = 0.8, 95% CI = 0.5–1.3, P = 0.351; CSS: HR = 0.7, 95% CI = 0.4–1.2, P = 0.259) and multi-organ metastases (OS: HR = 0.8, 95% CI = 0.5–1.3, P = 0.359; CSS: HR = 0.7, 95% CI = 0.4–1.2, P = 0.179) between surgery to primary site group and no-surgery to primary site group. Conclusion: we described the metastatic patterns of mRPCC and the prognosis outcomes of DL metastases, surgery to primary site and chemotherapy. Our findings provide more information for clinical therapeutic intervention and translational study designs.

Object To better establish the role of stereotactic radiosurgery (SRS) in treating patients with 10 or more intracranial metastases, the authors assessed clinical outcomes and identified prognostic factors associated with survival and tumor control in patients who underwent radiosurgery using the Leksell Gamma Knife Perfexion (LGK PFX) unit. Methods The authors retrospectively reviewed data in all patients who had undergone LGK PFX surgery to treat 10 or more brain metastases in a single session at the University of Pittsburgh. Posttreatment imaging studies were used to assess tumor response, and patient records were reviewed for clinical follow-up data. All data were collected by a neurosurgeon who had not participated in patient care. Results Sixty-one patients with 10 or more brain metastases underwent SRS for the treatment of 806 tumors (mean 13.2 lesions). Seven patients (11.5%) had no previous therapy. Stereotactic radiosurgery was the sole prior treatment modality in 8 patients (13.1%), 22 (36.1%) underwent whole-brain radiation therapy (WBRT) only, and 16 (26.2%) had prior SRS and WBRT. The total treated tumor volume ranged from 0.14 to 40.21 cm3, and the median radiation dose to the tumor margin was 16 Gy. The median survival following SRS for 10 or more brain metastases was 4 months, with improved survival in patients with fewer than 14 brain metastases, a nonmelanomatous primary tumor, controlled systemic disease, a better Karnofsky Performance Scale score, and a lower recursive partitioning analysis (RPA) class. Prior cerebral treatment did not influence survival. The median survival for a patient with fewer than 14 brain metastases, a nonmelanomatous primary tumor, and controlled systemic disease was 21.0 months. Sustained local tumor control was achieved in 81% of patients. Prior WBRT predicted the development of new adverse radiation effects. Conclusions Stereotactic radiosurgery safely and effectively treats intracranial disease with a high rate of local control in patients with 10 or more brain metastases. In patients with fewer metastases, a nonmelanomatous primary lesion, controlled systemic disease, and a low RPA class, SRS may be most valuable. In selected patients, it can be considered as first-line treatment.
