RESUMEN
BACKGROUND: Head and neck carcinoma of unknown primary (CUP) represents a challenging diagnostic process when standard work-up fails to identify the primary tumour site. The aim of this systematic review and meta-analysis was to evaluate the diagnostic utility and complication profile of transoral robotic surgery (TORS) tongue base mucosectomy (TBM) in the management of CUP. PATIENTS AND METHODS: An electronic database search was performed in the EMBASE, MEDLINE, PubMed and Cochrane databases. A meta-analysis of proportions was performed to obtain an estimate of the overall proportion for the detection and complication rates. RESULTS: Nine studies representing 235 patients with CUP who had TORS TBM were included in the final analysis. The overall pooled tumour detection rate was 66.2% [95% confidence interval (CI) 56.1-75.8]. The incidence of tumour detection in human papilloma virus (HPV)-positive cases (81.5%, 95% CI 60.8-96.4) was significantly higher than HPV-negative cases (2.3%, 95% CI 0.00-45.7). Weighted overall complication rate was 11.4% (95% CI 7.2-16.2). The majority were grade I or II (80%) according to the Clavien-Dindo classification. CONCLUSIONS: This meta-analysis suggests TORS to be safe and effective in localising the primary tumour site in patients with CUP. While the current data supports the use of TORS in patients who are HPV positive, larger numbers of HPV-negative cases are required to determine the true diagnostic effect with TORS before any valid conclusions can be inferred in this particular subgroup. Further research should focus on high quality prospective trials with stringent methodological work-up to minimise heterogeneity and allow for more accurate statistical analysis.

BACKGROUND: Transoral Robotic Surgery (TORS) and radiotherapy are considered oncologically equivalent primary treatment options for early-stage HPV-positive oropharyngeal squamous cell carcinoma (OPSCC). Quality of Life (QoL) and Patient Reported Outcome Measures (PROMs) are therefore imperative in supporting clinical decision-making and optimising patient-centred care. The aim of this article is to evaluate how these primary treatment modalities compare in terms of QoL. MATERIALS AND METHODS: Systematic review and meta-analysis of studies comparing primary TORS and primary radiotherapy for OPSCC using validated QoL tools. Swallowing and global QoL were the primary endpoints with secondary endpoints including all other QoL domains. An inverse variance random-effects model was employed to calculate the weighted estimate of the treatment effects across trials. RESULTS: A total of six studies collectively reporting on 555 patients were included (n = 236 TORS and n = 319 radiotherapy). Meta-analysis showed no significant difference for swallowing (mean difference = -0.24, p = 0.89) and global QoL (mean difference = 4.55, p = 0.14). For the remaining QoL domains (neck/shoulder impairment, neurotoxicity, voice, xerostomia, speech, and distress), the scarcity of data did not permit meta-analysis. However, the existing data showed no significant difference for any except for xerostomia where TORS appears favourable in the sole study reporting on this. CONCLUSIONS: TORS and radiotherapy appear to be comparable primary treatment options for early stage OPSCC when it comes to QoL. However, a substantial proportion of patients in the TORS group received adjuvant (chemo)radiotherapy rendering it difficult to establish the 'true' QoL outcomes following surgery alone. There are also minimal studies reporting QoL outcomes beyond swallowing and global QoL. Further research is therefore needed, including more randomised trials adequately powered to detect differences in QoL outcomes.

BACKGROUND: Clinical guidelines list active fungal infection and sepsis as contraindications to liver transplantation due to the risk of worsening infection with immunosuppression postoperatively. Mortality from systemic opportunistic infections in transplant recipients is high, approaching 100% for disseminated aspergillosis. However, the optimal duration of treatment required before transplant is unclear. Additionally, delaying surgery while the infection is treated risks death from hepatic decompensation and physical deconditioning, preventing progression to transplantation. CASE REPORT: Here, we present a patient who underwent successful repeat liver transplantation for recurrent autoimmune hepatitis and graft rejection while undergoing treatment for disseminated aspergillosis and nocardiosis. He had pulmonary, hepatic, and central nervous system involvement. He had received 2 months of antimicrobials but had ongoing radiologic evidence of infection when listed for retransplantation. He remains well and infection-free 1 year postoperatively. CONCLUSION: Few cases of successful liver transplantation in the setting of disseminated aspergillosis have been reported previously. To our knowledge, this is the first successful liver transplant in a patient with disseminated nocardial infection.
