Predictors of progression in high-grade appendiceal or colorectal peritoneal carcinomatosis after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

BACKGROUND: Long-term survival of patients with appendiceal or colorectal peritoneal carcinomatosis (PC) may be achieved by combining cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). Unfortunately, such favorable outcomes are realized in a minority of patients. Given the morbidity of the CRS/HIPEC and the uncertain role of postresection systemic therapy, it is important that prognostic factors in high-grade PC be clearly defined. METHODS: This single center, retrospective, cohort study examined the outcomes of CRS/HIPEC performed on patients with high-grade PC secondary to appendiceal or colorectal adenocarcinoma between 2007 and 2013. Cox regression analysis was utilized to evaluate the association between potential prognostic factors [age, sex, primary site, lymph node (LN) status, peritoneal cancer index (PCI) score, completeness of cytoreduction score (CC score), number of visceral resections, and systemic chemotherapy] and progression-free survival (PFS). RESULTS: A total of 70 patients with high-grade appendiceal or colorectal PC underwent CRS/HIPEC during the study period; 82.9 % underwent complete (CC-0) cytoreduction with a median PFS of 9.7 months. Positive LNs at the time of CRS/HIPEC were predictors of worse PFS on univariate and multivariate analysis. No association was demonstrated between pre- or post-HIPEC systemic chemotherapy and PFS. CONCLUSIONS: High-grade PC secondary to appendiceal or colorectal adenocarcinoma can be managed with CRS/HIPEC. The number of LN metastases at the time of CRS/HIPEC is the strongest predictor of progression and must be considered when determining patient eligibility for this aggressive treatment.

Emergency Department Pain Management in the Older Adult.

Pain assessment and management in older adults is complex and requires evaluation and consideration of the type of pain, the acuity of the condition, comorbidities, and medications. Many older adults do not receive appropriate therapy for painful conditions in the emergency department (ED). This brief review article is focused on pharmacologic agents, drug-drug interactions, drug-disease interactions, and approaches in the management of painful conditions seen in older adults in the emergency department. Recommendations for specific painful conditions such as fragility fractures are discussed.

Lack of documentation of evidence-based prognostication in cancer patients by inpatient palliative care consultants.

BACKGROUND: Prognostication plays a key role in palliative care (PC). It is critical for advance care planning, determining hospice eligibility, and communication. In contrast to subjective clinical prognostication, evidence-based prognostication (EBP) uses existing validated data to quantify prognosis; however, the extent to which PC providers use EBP is limited. OBJECTIVE: The objective was to analyze documentation of EBP by PC providers in the absence of an inpatient consultation note template at a single academic medical center. METHODS: We retrospectively evaluated prognostic documentation of inpatient PC consultations on oncology patients at a single academic hospital. Ratings of Eastern Cooperative Oncology Group (ECOG) Scale, Karnofsky Performance Scale (KPS), Palliative Performance Scale, and/or activities of daily living (ADLs) were considered documentation of functional status. PC-specific documentation of EBP included the Palliative Prognostic Index and/or Palliative Prognostic Score. RESULTS: There were 412 inpatient PC consultations for oncology patients (2012-2013). Reasons for consultation included goals of care (n=108), symptom management (n=181), or both (n=123). In the absence of a note template, functional status was documented in 6% (n=24) of consultation notes, while no consultation notes contained EBP documentation of the Palliative Prognostic Index and Palliative Prognostic Score. CONCLUSION: This retrospective analysis conducted at a single academic medical center suggests poor documentation by PC providers of EBP in the absence of a consultation note template. Research and educational opportunities exist to evaluate barriers to EBP utilization and documentation by PC providers.

Novel investigational biologics for the treatment of cancer cachexia.

INTRODUCTION: Cancer cachexia is a complex multifactorial syndrome characterized by ongoing, irreversible skeletal muscle loss, leading to progressive functional impairment. Several investigational biologics targeting key inflammatory pathways and/or the myostatin/activin type II receptor pathway are in development. AREAS COVERED: Novel therapies include ALD518, MABp1, IP-1510, OHR/AVR118, bimagrumab and REGN1033 and are discussed. For each investigational therapy, the mechanism of action, preclinical data, cachexia definition, indication and clinical data are discussed. EXPERT OPINION: A critical look of the study protocols and two key challenges limiting the successful evaluation of these agents include: i) lack of a clinically meaningful cachexia definition; and ii) identification and treatment of cachexia in late stage. We describe our observations and clinical experience in an effort to redirect and promote successful strategies to evaluate these novel investigational biologics.

Rapidly progressive subcutaneous metastases from gallbladder cancer: insight into a rare presentation in gastrointestinal malignancies.

BACKGROUND: Gallbladder cancer (GBCA) is the most common malignancy of the biliary tract. It has an aggressive biology that results in the ability to spread, seed and grow in disparate environments. It can metastasize via lymphatic, hematogenous, and peritoneal seeding. However, GBCA metastasis to distant subcutaneous sites is extremely rare. CASE PRESENTATION: This case report describes the presentation of metastatic GBCA with rapidly progressive subcutaneous metastases. A 58-year-old woman presented with acute onset right upper quadrant abdominal pain. Computed tomography (CT) revealed a calcified and thickened gallbladder with cholelithiasis and presumed cholecystitis. Diagnostic laparoscopy revealed a gallbladder mass. Biopsies were consistent with GBCA. The patient was referred to our cancer center for further surgical management. However, she was found to have rapidly growing subcutaneous nodules in the shoulders, chest, abdomen, and buttocks. Positron emission tomography (PET) demonstrated that these were fluorodeoxyglucose (FDG)-avid. A core needle biopsy of a chest wall lesion was consistent with metastatic GBCA. Therefore, the patient was diagnosed with stage IVB GBCA and was initiated on systemic chemotherapy. DISCUSSION: GBCA is known to have an incredible propensity to grow within the peritoneal cavity, as well as along needle biopsy tracts and at laparoscopic port sites. Several case reports have demonstrated that GBCA also has the potential to metastasize to distant subcutaneous sites, most often including breast metastases, while the current cases represents a more diffuse pattern of spread. CONCLUSIONS: GBCA belongs to the short list of solid visceral malignancies that have the potential to develop remote subcutaneous metastases.
