OBJECTIVE: Complete resection is the curative treatment choice for recurrent gynecological malignancies. Laterally extended endopelvic resection (LEER) is an effective surgical salvage therapy for lateral recurrence. However, when a recurrent tumor occupies the ischial spine and sacrum, LEER is not indicated, and surgical salvage therapy is abandoned. Theoretically, complete resection of such a tumor is possible by additional pelvic bone resection along with the standard LEER. Nevertheless, owing to the anatomical complexities of the beyond-LEER procedure, 2 major issues should be solved: sciatic nerve injury and tumor disruption during pelvic bone amputation. To overcome these technical challenges, we applied a multidirectional beyond-LEER approach, a novel salvage surgical procedure, with an aim of demonstrating its technical feasibility.
METHODS: We created a simulation model of a laterally recurrent tumor that occupied the right ischial spine and sacrum in a Thiel-embalmed cadaver.
RESULTS: Multidirectional approaches, including laparoscopic, perineal, and dorsal phases, were safely applied. We laparoscopically marked the L4-L5-S1 complex and S2 nerve with different colored tapes, and by pulling them out into a dorsal surgical field, the sciatic nerve was safely preserved. The dissection lines of the multidirectional approaches were aligned using tapes as landmarks, and complete tumor clearance without tumor disruption was accomplished. By following the cadaveric training, the first laparoscopic-assisted beyond-LEER procedure was successfully performed in a patient with recurrent ovarian cancer.
CONCLUSIONS: Using a Thiel-embalmed cadaver, we demonstrated the technical feasibility of a sciatic nerve-preserved beyond-LEER procedure, which was successfully performed in a patient with recurrent ovarian cancer.

OBJECTIVE: Injection laryngoplasty (IL) has been widely used as an initial treatment option for unilateral vocal fold paralysis (UVFP). An additional (second) IL is considered a salvage treatment for unsatisfactory outcomes of initial IL resulting from inadequate injection or early resorption of the injection material. This study aims to evaluate the efficacy of additional IL, distinguishing between \"salvage\" (within 4 months) and \"repeated\" injections (beyond 4 months), and to analyze prognostic factors for successful outcomes.
METHODS: This retrospective study involved patients who received IL at Asan Medical Center from January 2014 to December 2020. Voice parameters were collected after each procedure, and those who conducted the statistical analysis were blinded to the study subjects. Among the 65 patients who underwent additional IL, 51 patients were enrolled in this study. Postinjection grade, roughness, breathiness, asthenia, strain (GRBAS) scales were used to determine satisfactory treatment outcomes. Success of the additional IL was defined as a postinjection grade of dysphonia score of 0 or 1, with a reduction in grade compared with the preinjection grade.
RESULTS: The mean age of the patients was 61.6 years. Out of a total of 51 patients, 37 were men participating in the study. The odds ratio represents the likelihood of success in the second IL. Improved voice outcome after the additional IL was maintained in 23 (45%) patients. Compared with the failure group, the success group had a longer injection time interval between the initial and additional injection (9.1 vs. 7.4 months, respectively, p = 0.010). The success group had a higher proportion of patients with injection intervals >6 months (73.9% vs. 42.9%, p = 0.026). Logistic regression analysis revealed an injection interval >6 months had an odds ratio of 0.265 (confidence interval: 0.080-0.874, p = 0.029).
CONCLUSIONS: Additional injections would benefit the patients whose voice outcomes are maintained for a longer period (>6 months) after the first injection.

Management of recurrent prostate cancer following radiotherapy and subsequent radical prostatectomy poses considerable challenges due to potential complications for patients. Focal therapies have emerged as a burgeoning approach in prostate cancer treatment. Research indicates that ablative therapies exhibit encouraging oncological efficacy while maintaining acceptable functional outcomes in salvage interventions. Here, we present a contemporary review of focal therapy treatment modalities as well as oncologic and functional outcomes.

This systematic review and meta-analysis investigated the impact of salvage surgery on 5-year overall survival (OS) and prognostic factors in recurrent oral cavity cancer (rOCC) patients. Relevant literature before May 2022 was reviewed, including retrospective cohort studies and observational studies comparing salvage surgery to other treatments. Risk-of-bias assessments were conducted using the Newcastle-Ottawa scale. Statistical and subgroup analyses assessed the impact of salvage surgery on 5-year OS and prognostic factors. 3036 documents were initially retrieved, with 14 retrospective cohort studies (2069 participants) included. Meta-analysis of 5-year OS in salvage surgery patients yielded a rate of 43.0%. Subgroup analysis showed higher OS in Asians (49.9% vs. 36.9%, p = 0.003) and late-relapse (63.8% vs. 30.0%, p = 0.004) groups. Prognostic factors revealed hazards associated with nodal recurrence, extranodal extension, and perineural invasion. Salvage surgery is a viable option for rOCC patients, showing favorable 5-year OS outcomes. Low publication bias enhances study reliability, but its single-arm design limits conclusions on salvage surgery superiority over other treatments.

OBJECTIVE: To investigate the safety and effectiveness of radiotherapy for advanced upper tract urothelial carcinoma (UTUC) patients intolerant to chemotherapy.
METHODS: Data for 21 patients with advanced UTUC intolerant to chemotherapy were retrospectively collected. All patients were treated with conventionally fractionated radiotherapy (50-70 Gy/20-33 f) or partial-SABR boost to the lesions (50-60 Gy/20-25 f with tumor center boosted with 6-8 Gy/f, 3-5 f) for bulky tumors.
RESULTS: The median age was 75 years (range, 58-87 years). Primary tumor resection was performed for all patients and none underwent metastatic resection. Seventeen (81%) patients had oligometastasis (1-5 metastases) at diagnosis. Eighteen (85.7%) received irradiation to all tumor lesions. Lymph node metastasis was predominant in the whole group (17/21). Other lesions were distributed as local recurrence (7/21), bone metastases (2/21) and abdominal wall/muscle (2/21). The median follow-up time was 38.5 months (interquartile range, 15.2-48.7 months). Rate of local control (LC), progression-free survival (PFS) and overall survival (OS) of the whole group at 1 year were 90%, 46.6%, and 80.4%, respectively. At 3 years, LC, PFS and OS were 65.6%, 26.6%, and 40.9%, respectively. Fourteen patients developed acute mild gastrointestinal toxicity, generally of grade 1-2; 8 patients developed acute grade 1-2 hematological toxicity, consisting mainly of anemia and leukopenia. No grade 3 or higher acute or late toxicities were observed.
CONCLUSIONS: For patients with advanced UTUC who are not able to tolerate chemotherapy, radiotherapy is a safe treatment and can achieve good local tumor control.

Objective: To investigate the efficacy and safety of liposomal amphotericin B (L-AmB) for the salvage treatment of invasive fungal disease (IFD) in patients with hematological diseases. Methods: Data were retrospectively collected from 80 patients with hematological issues treated with L-AmB between June 2023 and December 2023 after failure of previous antifungal therapy. Baseline patient information, clinical efficacy, and factors affecting the efficacy of L-AmB were analyzed by logistic regression. Moreover, adverse effects associated with L-AmB were evaluated. Results: Among the 80 patients, 9 (11.2%) had proven IFD, 43 (53.8%) had probable IFD, and 28 (35.0%) had possible IFD. The efficacy rate of L-AmB salvage therapy for IFD was 77.5%, with a median daily dose of 3 (range: 1-5) mg·kg(-1)·d(-1) and a median dosing course of 14 (range: 8-25) days. Multivariate logistic regression analysis showed that the disease remission status (OR=4.337, 95% CI 1.167-16.122, P=0.029) and duration of medication (OR=1.127, 95% CI 1.029-1.234, P=0.010) were independent factors affecting the efficacy of L-AmB. The incidence of infusion reactions associated with L-AmB, including fever and chills, was 5.0%. The incidence of hypokalemia was 28.8% (predominantly grades 1-2), and the incidence of nephrotoxicity was 11.3% (predominantly grades 1-2) . Conclusion: L-AmB is safe and effective in the treatment of patients with IFD who are intolerant to or who have experienced no effect of previous antifungal therapy, with a low rate of adverse reactions.

OBJECTIVE: Technical graft loss, usually thrombotic in nature, accounts for most of the pancreas grafts that are removed early after transplant. Although arterial and venous thrombosis can occur, the vein is predominantly affected, with estimated overall rate of thrombosis of 6% to 33%. In late diagnosis, the graft will need to be removed because thrombectomy will not restore its functionality. However, in early diagnosis, a salvage procedure should be attempted.
METHODS: We conducted a retrospective, descriptive analysis of a prospective database of patients who underwent pancreas transplant from April 2008 to June 2020 at a single center. We evaluated post-transplant clinical glucose levels, imaging, treatment, and outcomes. We also performed a systematic review of publications for endovascular treatment of vascular graft thrombosis in pancreas transplant.
RESULTS: In 67 pancreas transplants analyzed, 13 (19%) were diagnosed with venous thrombus. In 7 of 13 patients (54%), systemic anticoagulation was prescribed because of a non-occlusive thromboses, resulting in complete resolution for all 7 patients. Six patients (46%) required endovascular thrombectomy because of the presence of complete occlusive thrombosis; 4 of these patients (67%) needed a second procedure because of recurrence of the thrombosis. One of the 6 patients (17%) required a surgical approach, resulting in successful removal of the recurrent clot. Twelve of the 13 grafts (92%) were rescued. Graft survival at 1 year was 84%; graft survival at 3, 5, and 10 years remained at 70%.
CONCLUSIONS: Pancreas vein thrombosis represents a frequent surgical complication and remains as a challenging problem. In our experience, early diagnoses and an endovascular approach combined with aggressive medical treatment and follow-up can be used for successful treatment and reduce graft loss.

BACKGROUND: Prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) is becoming standard of care for men with biochemical recurrence (BCR) of prostate cancer. The implications of a negative PSMA PET/CT scan in this population remain unclear. This study aims to assess the outcome of patients with BCR post radical prostatectomy (RP) who have negative [18F]DCFPyL PET/CT scan at relapse.
METHODS: This is a post-hoc subgroup analysis of a prospective non randomized clinical trial. One hundred and one patients (median age, 75 years) with BCR after RP, who tested negative on [18F]DCFPyL PET/CT and subsequently either underwent salvage radiotherapy (sRT) with or without androgen deprivation therapy (ADT) or were followed without active treatment, were included. Freedom from progression (FFP) after negative PSMA PET/CT was determined based on follow-up imaging selected as per clinical practice. Uni- and multivariate Cox regression analyses were performed to examine the association of patients\' characteristics, tumor-specific variables, and treatment with clinical progression at the last follow-up. FFP at 1-, 2-, and 3-year were reported using Kaplan Meier analysis.
RESULTS: The median PSA level at PET/CT was 0.56 ng/mL (range, 0.4-11.3). Sixty five (64%) patients were followed without receiving further treatment, and 36 (36%) received sRT (18% to the prostate bed only and 18% to the prostate bed and pelvic lymph nodes) within 3 months of the PSMA PET. Seventeen of the sRT patients (17 of 36, 47%) received concomitant androgen deprivation therapy (ADT). Median follow-up was 39 months. Subsequent clinical progression was detected in 21 patients (21%), with 52% in pelvic lymph nodes, 52% in the prostatic fossa, 19% in distant lymph nodes, 14% in lungs, and 10% in bones. The FFP was 95% (95% CI: 91%-99%) at 12 months, 87% (95% CI: 81%-94%) at 24 months, and 79% (95% CI: 71%-88%) at 36 months. Multivariate Cox regression analysis revealed that an initial International Society of Urological Pathology (ISUP) grade 5 was significantly associated with clinical progression at the last follow-up (hazard ratio, 5.1, P value, 0.04). Furthermore, the receipt of sRT correlated significantly with lower clinical progression at the last follow-up (hazard ratio, 0.2, P value, 0.03), whereas other clinical and tumor-specific parameters did not. Following surveillance-only and sRT, 29% (19 of 65) and 6% (2 of 36) of patients, respectively, showed clinical progression. In the sRT group, no significant difference was observed in FFP between patients who underwent sRT to the prostatic fossa versus those who received sRT to the prostatic fossa and pelvic lymph nodes, although the numbers in these groups were small.
CONCLUSIONS: This study suggests that salvage radiotherapy is associated with a decreased or delayed clinical progression in patients with biochemical recurrence following radical prostatectomy who have negative PSMA PET/CT scan results. The analysis also underscores the prognostic significance of the initial ISUP grade, with ISUP grade 5 being associated with worse outcomes.

BACKGROUND: Thrombotic microangiopathy (TMA) is a rare complication after lung transplantation (LT) that has seldom been characterized in detail. Recent evidence has linked TMA other than primary atypical hemolytic uremic syndrome (aHUS) with hyperactivation of the complement alternative pathway. The focus of this investigation was to analyze the treatment response with eculizumab in TMA after LT.
METHODS: Case series where we have studied 11 patients with TMA after LT from 2 Spanish tertiary healthcare centers. Clinical data and response rates to eculizumab are provided.
RESULTS: The main indication for lung transplant was chronic obstructive pulmonary disease (COPD) (36%) and most cases (82%) received bilateral LT. The median time to TMA diagnosis was 11.6 months (4.7-28.9) and the TMA trigger in the majority of cases (73%) was immunosuppressive drugs. Platelet and hemoglobin nadir were 58 × 103/µL (24-108) and 7.7 g/dL (7.1-7.9), respectively. All cases presented acute kidney injury (AKI) with a median creatinine of 4 mg/dL (3.2-4.8) and 54.5% required acute dialysis. Eculizumab was started after a median time of 8 days (6-14) with a median duration of 3 weeks (2-8). Complete TMA response was observed in 7 (63.6%) cases and hematologic response in 10 (90.9%). The time to hematologic and renal response was 23 days (13-29) and 28 days (14-46), respectively.
CONCLUSIONS: TMA after LT is infrequent but potentially devastating. Our findings suggest that short cycles of eculizumab may be effective for severe TMA after LT.
