The management of pharyngocutaneous fistula is challenging. We typically treat postlaryngectomy pharyngocutaneous fistulas with a pedicled pectoralis major flap transfer. This study analyzed the outcomes of our surgical treatments for pharyngocutaneous fistula to propose considerations for surgical strategies.

This retrospective review included all patients who underwent surgical repair of a postlaryngectomy pharyngocutaneous fistula at the National Cancer Center Hospital East in Kashiwa, Japan, from January 2005 to December 2019.

The final analysis included 33 cases (median age, 71 years). Twenty-two cases had a history of radiotherapy to the head and neck region. Wound closures were performed with a pedicled pectoralis major musculocutaneous flap (n = 26) or pedicled pectoralis major muscle flap (n = 7). In 1 case, a deltopectoral flap was combined with the pectoralis major musculocutaneous flap. Dinaciclib CDK inhibitor The median total operation time was 236 minutes, the median blood loss during surgery was 144 mL, and the trated that pedicled pectoralis major flap transfer is useful for the treatment of postlaryngectomy pharyngocutaneous fistula.
Our surgical treatment for postlaryngectomy pharyngocutaneous fistula succeeded in 31 of 33 cases (94%). This study demonstrated that pedicled pectoralis major flap transfer is useful for the treatment of postlaryngectomy pharyngocutaneous fistula.
To evaluate the outcomes of metastasis-directed treatment (MDT) using stereotactic body radiotherapy (SBRT) for bone-only oligometastasis (OM) detected with gallium prostate-specific membrane antigen (68Ga-PSMA) PET/CT in castration-sensitive prostate cancer (PC) patients.

In this multi-institutional study, clinical data of 74 PC patients with 153 bone lesions who were undergoing MDT were retrospectively evaluated. Twenty-seven patients (36.5%) had synchronous, and 47 (63.5%) had metachronous OM. All patients had PC with 5 metastases or fewer detected by 68Ga-PSMA PET/CT and treated using SBRT with a median dose of 20 Gy. The prognostic factors for PC-specific survival (PCSS) and progression-free survival (PFS) were analyzed.

The median follow-up was 27.3 months. Patients with synchronous OM were older and received higher rates of androgen deprivation therapy after SBRT compared with patients with metachronous OM. The 2-year PCSS and PFS rates were 92.0% and 72.0%, respectively. A prostate-specific antigen (PSA) decline was observed in 56 patients (75.7%), and 48 (64.9%) had a PSA response defined as at least 25% decrease of PSA after MDT. The 2-year local control rate per lesion was 95.4%. In multivariate analysis, single OM and PSA response after MDT were significant predictors for better PCSS and PFS. In-field recurrence was observed in 4 patients (6.5%) with 10 lesions at a median of 13.1 months after MDT completion. No serious late toxicity was observed.

We demonstrated that SBRT is an efficient and well-tolerated treatment option for PC patients with 5 bone-only oligometastases or fewer detected with 68Ga-PSMA PET/CT.

A 44-year-old man after combined left temporal low-grade glioma treatment presented with daily multiple series of seizures. MRI demonstrated diffuse cortical swelling in the left frontal lobe with intensive gyral enhancement. PET with [11C]methionine (PET-MET) revealed increased radiotracer uptake strictly confined to the cortical ribbon of the left cerebral hemisphere, which persisted for 3 months. Tumor recurrence was suggested, and biopsy was performed. No evidence of recurrent tumor was found. During a 2-year follow-up, a diffuse gyral enhancement in the left hemisphere has persisted on MRI; PET has shown high [11C]methionine uptake in the left frontal and parietal cortex with gradual positive dynamics.

A left pulmonary nodule was identified by CT scan in a 53-year-old woman who had a car accident 10 days earlier. 18F-FDG PET/CT showed multiple FDG-avid lesions located at the left lung nodule, mediastinal lymph nodules, and L4 vertebral body. 68Ga-FAPI PET/CT was performed for further evaluation. However, 68Ga-FAPI demonstrated intense FAPI uptake in the accident-related fracture of the L4 vertebral body. This case documents that the fracture of the vertebral body may cause FAPI uptake, and nuclear clinicians evaluating 68Ga-FAPI imaging should be aware of this potential pitfall.

A 76-year-old woman underwent 18F-florapronol (18F-FC119S, an amyloid β imaging PET agent) PET, owing to cognitive impairment. 18F-florapronol PET images revealed an incidental 18F-florapronol uptake in the right frontal lobe. A well-enhancing extra-axial mass in the right frontal lobe was observed on MRI scans, suggesting a meningioma. After excision of the tumor, the biopsy results confirmed it as a meningothelial meningioma.
