Metaanalysis of survival, complications, and imaging response following chemotherapy-based transarterial therapy in patients with unresectable intrahepatic cholangiocarcinoma.

PURPOSE: Unresectable intrahepatic cholangiocarcinoma represents a devastating illness with poor outcomes when treated with standard systemic therapies. Several smaller nonrandomized outcomes studies have been reported for such patients undergoing transarterial therapies. A metaanalysis was performed to assess primary clinical and imaging outcomes, as well as complication rates, following transarterial interventions in this patient population. MATERIALS AND METHODS: By using standard search techniques and metaanalysis methodology, published reports (published in 2012 and before) evaluating survival, complications, and imaging response following transarterial treatments for patients with unresectable intrahepatic cholangiocarcinoma were identified and evaluated. RESULTS: A total of 16 articles (N = 542 subjects) met the inclusion criteria and are included. Overall survival times were 15.7 months ± 5.8 and 13.4 months ± 6.7 from the time of diagnosis and time of first treatment, respectively. The overall weighted 1-year survival rate was 58.0% ± 14.5. More than three fourths of all subjects (76.8%) exhibited a response or stable disease on postprocedure imaging; 18.9% of all subjects experienced severe toxicities (National Cancer Institute/World Health Organization grade ≥ 3), and most experienced some form of postembolization syndrome. Overall 30-day mortality rate was 0.7%. CONCLUSIONS: As demonstrated by this metaanalysis, transarterial chemotherapy-based treatments for cholangiocarcinoma appears to confer a survival benefit of 2-7 months compared with systemic therapies, demonstrate a favorable response by imaging criteria, and have an acceptable postprocedural complication profile. Such therapies should be strongly considered in the treatment of patients with this devastating illness.

Use of acupuncture with acupressure in addition to standard-of-care cryotherapy to decrease chemotherapy-associated neuropathy in patients with gastrointestinal malignancies receiving oxaliplatin-based chemotherapy: Study protocol for a randomized, controlled pilot and feasibility study.

BACKGROUND: Oxaliplatin is a key chemotherapeutic agent in the treatment of local and metastatic gastrointestinal (GI) malignancies. Dose density and treatment adherence can be limited by chemotherapy-induced peripheral neuropathy (CIPN). Early research suggests CIPN incidence and severity may be mitigated by acupuncture, but rigorous data in GI oncology patients is limited. Here, we describe the protocol of a randomized, waitlist-controlled pilot study testing the use of preemptive of acupuncture plus acupressure to decrease CIPN and chemotherapy-related toxicities. METHODS: Patients with a GI malignancy (n = 56) with planned 5-fluorouracil (5-FU) and oxaliplatin IV (FOLFOX, FOLFIRINOX) every 2 weeks are being recruited. Additional concurrent anti-neoplastic agents may be used. Enrolled patients are randomized 1:1 to a 3-month intervention of Arm A: acupuncture with acupressure and standard-of-care treatment, or Arm B: standard-of-care alone. In Arm A, on days 1 and 3 of each chemotherapy cycle a standardized acupuncture protocol is administered and patients are taught self-acupressure to perform daily between chemotherapy treatments. Patients in both arms are given standard-of-care oral and peripheral (hands/feet) ice chip cryotherapy during oxaliplatin administration. CIPN and other symptoms are assessed at baseline, 6 weeks, and 3 months from registration. The primary endpoint is CIPN severity at 3 months (EORTC-CIPN 20). Additional endpoints evaluate CIPN incidence (CTCAE, Neuropen, tuning fork); incidence of pain, fatigue, nausea, oral dysesthesia, and anxiety; and feasibility (recruitment, retention, adherence, acceptability). If warranted, trial results will inform the design of a multi-center trial to expand testing of the intervention to a larger patient cohort.
