Metastatic Pancreatic Cancer: ASCO Clinical Practice Guideline Update.

Purpose In 2016, ASCO published a guideline to assist in clinical decision making in metastatic pancreatic cancer for initial assessment after diagnosis, first- and second-line treatment options, palliative and supportive care, and follow-up. The purpose of this update is to incorporate new evidence related to second-line therapy for patients who have experienced disease progression or intolerable toxicity during first-line therapy. Methods ASCO convened an Expert Panel to conduct a systematic review of the literature on second-line therapy published between June 2015 and January 2018. Recommendations on other topics covered in the 2016 Metastatic Pancreatic Cancer Guideline were endorsed by the Expert Panel. Results Two new studies were found that met the inclusion criteria. Recommendations For second-line therapy, gemcitabine plus nanoparticle albumin-bound paclitaxel should be offered to patients with first-line treatment with FOLFIRINOX (leucovorin, fluorouracil, irinotecan, and oxaliplatin), an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 to 1, and a favorable comorbidity profile; fluorouracil plus nanoliposomal irinotecan can be offered to patients with first-line treatment with gemcitabine plus NAB-paclitaxel, an ECOG PS of 0 to 1, and a favorable comorbidity profile; fluorouracil plus irinotecan or fluorouracil plus oxaliplatin may be offered when there is a lack of availability of fluorouracil plus nanoliposomal irinotecan; gemcitabine or fluorouracil should be offered to patients with either an ECOG PS of 2 or a comorbidity profile that precludes other regimens. Testing select patients for mismatch repair deficiency or microsatellite instability is recommended, and pembrolizumab is recommended for patients with mismatch repair deficiency or high microsatellite instability tumors. Endorsed recommendations from the 2016 version of this guideline for computed tomography, baseline performance status and comorbidity profile, defining goals of care, first-line therapy, and palliative care are also contained within the full guideline text.

Metastatic Pancreatic Cancer: American Society of Clinical Oncology Clinical Practice Guideline.

PURPOSE: To provide evidence-based recommendations to oncologists and others for the treatment of patients with metastatic pancreatic cancer. METHODS: American Society of Clinical Oncology convened an Expert Panel of medical oncology, radiation oncology, surgical oncology, gastroenterology, palliative care, and advocacy experts to conduct a systematic review of the literature from April 2004 to June 2015. Outcomes were overall survival, disease-free survival, progression-free survival, and adverse events. RESULTS: Twenty-four randomized controlled trials met the systematic review criteria. RECOMMENDATIONS: A multiphase computed tomography scan of the chest, abdomen, and pelvis should be performed. Baseline performance status and comorbidity profile should be evaluated. Goals of care, patient preferences, treatment response, psychological status, support systems, and symptom burden should guide decisions for treatments. A palliative care referral should occur at first visit. FOLFIRINOX (leucovorin, fluorouracil, irinotecan, and oxaliplatin; favorable comorbidity profile) or gemcitabine plus nanoparticle albumin-bound (NAB) -paclitaxel (adequate comorbidity profile) should be offered to patients with Eastern Cooperative Oncology Group performance status (ECOG PS) 0 to 1 based on patient preference and support system available. Gemcitabine alone is recommended for patients with ECOG PS 2 or with a comorbidity profile that precludes other regimens; the addition of capecitabine or erlotinib may be offered. Patients with an ECOG PS ≥ 3 and poorly controlled comorbid conditions should be offered cancer-directed therapy only on a case-by-case basis; supportive care should be emphasized. For second-line therapy, gemcitabine plus NAB-paclitaxel should be offered to patients with first-line treatment with FOLFIRINOX, an ECOG PS 0 to 1, and a favorable comorbidity profile; fluorouracil plus oxaliplatin, irinotecan, or nanoliposomal irinotecan should be offered to patients with first-line treatment with gemcitabine plus NAB-paclitaxel, ECOG PS 0 to 1, and favorable comorbidity profile, and gemcitabine or fluorouracil should be offered to patients with either an ECOG PS 2 or a comorbidity profile that precludes other regimens.

Isolated splenic metastasis from rectal carcinoma: a rare occurrence.

The presence of isolated splenic metastasis in rectal carcinoma is uncommon and usually presents as an asymptomatic mass, noted incidentally on imaging. Splenectomy is usually performed with the goal of curing metastatic disease. It is unclear if adjuvant chemotherapy affords any benefit, and the prognosis is unknown. The case of a young woman is reported, in whom an isolated metastatic lesion in the spleen was discovered 9 months after adjuvant chemotherapy for stage III rectal adenocarcinoma. The patient has remained disease-free for nearly 5 years following splenectomy and chemotherapy. To our knowledge, this is the fourth reported case in the English literature of an isolated splenic metastatic lesion from rectal cancer. We discuss the unique presentation, the importance of post-treatment surveillance, and the implementation of multi-modality treatment strategies in this young patient.
