Indications and results of liver resection and hepatic chemoembolization for metastatic gastrointestinal neuroendocrine tumors

BACKGROUND: We reviewed 36 patients with liver metastases from islet cell tumors of the pancreas (n = 18) and carcinoid tumors (n = 18) who were treated with surgical resection (n = 16) or hepatic chemoembolization (n = 20). METHODS: All resections were complete and included 4 lobectomies, 6 segmental resections, and 6 wedge resections. There were no operative deaths. RESULTS: Median survival has not yet been reached, and the actuarial 5-year survival rate is 70%. Prognostic variables associated with improved disease-free survival included prior resection of the primary tumor and 4 or fewer metastases resected (P <.05). With an average of 3 chemoembolization procedures per patient, 17 of 20 patients (90%) demonstrated either a significant radiographic response (n = 5), stabilization of tumor mass (n = 2), or improvement of clinical symptoms (n = 10). Factors related to a sustained response (more then 1 year) included surgical resection of the primary tumor, 4 or more chemoembolization procedures, and liver metastases of 5 cm or smaller. Median survival after treatment was 32 months (range, 7-63 months), and the actuarial 5-year survival rate was 40%. CONCLUSIONS: Surgical resection of metastatic neuroendocrine tumors provides the best chance for extended survival. Chemoembolization effectively improves clinical symptoms and, in selected patients, may provide sustained tumor control.     

Primary cancers of the small bowel: analysis of prognostic factors and results of surgical management

HYPOTHESIS: This study was done to review the clinical presentation, surgical management, pathologic features, and prognostic factors for primary small-bowel cancers. DESIGN: Retrospective case series. SETTING: Tertiary care, university hospital. PATIENTS: One hundred twenty-nine patients were surgically treated between January 1, 1977, and December 31, 2000. There were 73 men and 56 women, with a median age of 55 years (age range, 19-82 years). Median follow-up was 36 months. MAIN OUTCOME MEASURES: Presenting symptoms and signs, operations performed, and surgical pathologic features were analyzed and survival curves were generated. RESULTS: Clinical findings included abdominal pain (63%), vomiting (48%), weight loss (44%), and gastrointestinal tract bleeding (23%). The distribution of tumors by histological features was as follows: adenocarcinoma (33%), carcinoid tumor (29%), lymphoma (19%), and sarcoma (19%). Cumulative 5-year survival rate was 37% in the adenocarcinoma group, 64% in the carcinoid tumor group, 29% in the lymphoma group, and 22% in the sarcoma group. Significant prognostic predictors of overall survival for the entire cohort and for each tumor subtype included complete resection and American Joint Committee on Cancer tumor stage (P<.05). Patient age, tumor location, histological grade, and use of chemotherapy and radiation therapy did not significantly influence survival. Curative resections were accomplished in 83 patients (64%) with a median survival of 37 months compared with 46 patients undergoing incomplete or palliative resections with a median survival of 10 months (P<.05). Adjacent organ resection was required in 18 (22%) of the 83 patients undergoing potentially curative resections. The median time to recurrence was 16 months. Twenty-one patients (16%) developed associated primary cancers. CONCLUSIONS: Aggressive surgical resection in an attempt to achieve complete tumor removal seems warranted. Despite complete resections, patients with high-stage tumors remain at risk for recurrence.     

Biologic therapy for acrodermatitis continua of Hallopeau: Successful treatment with secukinumab and review of the literature

Acrodermatitis continua of Hallopeau (ACH) is a rare pustular psoriasis variant refractory to many conventional treatments. We report the successful treatment with secukinumab of a patient with a long history of ACH with marked onychodystrophy with frank pustulosis on the nail bed and with accompanying arthritis. Blockade of the IL‐17 receptor A has shown promise in the treatment of psoriatic erythroderma and generalized pustular psoriasis not responsive to conventional treatment. A rapid response was observed in our patient, in both skin lesions and arthritic symptoms, underlining the ability of secukinumab to improve symptoms beyond those of plaque psoriasis.     

Effectiveness and safety of ustekinumab in naïve or TNF-inhibitors failure psoriatic arthritis patients: a 24-month prospective multicentric study

The current prospective observational study aimed to evaluate the long-term (24 months), real-life effectiveness of ustekinumab in psoriatic arthritis (PsA). Consecutive patients with moderate-severe PsA and active psoriasis who begun ustekinumab treatment were evaluated prospectively (January 2015–March 2017). Clinimetric scores and biochemical values were assessed at baseline (T0), at 6 (T6), 12 (T12), and 24 (T24) months. Friedman test and generalized linear models were used to compare variables over time. Regression analysis to identify determinants of minimal disease activity (MDA) at T6 and of treatment discontinuation was conducted. Sixty-five patients (43.1% men; age 49.4?±?11.6 years) were enrolled; ustekinumab was prescribed as a first (20%), second (33.8%), third (26.5%), fourth (15.4%), or fifth (4.6%) line biological therapy. Significant decrease in tender/swollen joints, Visual Analogue Scale of pain (VASp) and general health (VASgh), Disease Activity in PsA (DAPSA), Psoriasis Area Severity Index (PASI), Leeds Enthesitis Index (LEI), Health Assessment Questionnaire modified for spondyloarthritis (HAQ-S), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) was achieved. MDA was reached by 30.7, 47.0, and 34.0% of patients respectively at T6, T12, and T24. In multivariable models, mono-oligoarthritis was independently associated to MDA at T6 (OR 9.02; 95% CI 1.41, 57.71), while baseline CRP (OR 1.12; 95% CI 1.00, 1.26) and LEI (OR 0.50; 95% CI 0.25, 0.97) to ustekinumab discontinuation. More patients used disease-modifying antirheumatic drugs at T0 (35.3%) than at T24 (8.5%). Only nine episodes of infection and no serious adverse events were registered. In a real-life clinical setting, ustekinumab was safe and effective in PsA. Comedication tapering was often possible.     

Ustekinumab for treatment of plaque psoriasis in a patient with Down syndrome

Down syndrome (DS) is the most common chromosomal disorder and a major cause of mental retardation. Down syndrome phenotype is complex and may present a combination of dysmorphic features, congenital heart disease and immunological deficiency. Psoriasis it has been noted to be 0.5%-8% in patients with DS and numerous factors can limit the use of therapeutic options, in particular long-term organ-specific toxicity, and the risk of opportunistic infections. It is still debated whether the use of biologics in the treatment of DS-related psoriasis is safe. We have valuated the efficacy and safety of ustekinumab treatment in-patient with DS suffering from plaque type psoriasis. A 31-year-old patient suffering from plaque type psoriasis since the age of 14, showed a PASI score of 12 after the failure of anti-TNF agents. We switched the patient to ustekinumab treatment at the standard dose of 45 mg subcutaneously initially and 4 weeks later, followed by 45 mg every 12 weeks. The patient showed a significant improvement of the PASI score already after 4 weeks of treatment and further improvements were observed throughout the treatment. We report the first case of DS-correlated psoriasis patient treated for a long-term period with various biologics, showing a satisfactory safety profile undergoing treatment. In our experience, ustekinumab has demonstrated a high efficacy, relatively rapid onset of action, favorable safety profile, and can be considered a good treatment option even after failure to respond to other biologic therapies in patient with DS.     

The effects of bevacizumab on postoperative complications in patients undergoing colorectal and pancreatic cancer resection

Bevacizumab (Avastin?; rhuMab VEGF), a monoclonal antibody targeting vascular endothelial growth factor (VEGF), has seen increased use in the perioperative treatment of colorectal and pancreatic cancer. Little is known, however, regarding its impact on surgical outcomes in patients undergoing resection. The objective of this review was to examine if the addition of bevacizumab to existing neoadjuvant regimens increases morbidity after cancer resection. J. Surg.
