Implementation and evaluation of a national quality improvement initiative in cancer surgery.

Background: In 2017, the Canadian Partnership Against Cancer, a Canadian federally sponsored organisation, initiated a national multijurisdictional quality improvement (QI) initiative to maximise the use of synoptic data to drive cancer system improvements, known as the Evidence for Surgical Synoptic Quality Improvement Programme. The goal of our study was to evaluate the outcomes, determinants and learning of this nationally led initiative across six jurisdictions in Canada, integrating a mix of cancer surgery disease sites and clinicians.

Methods: A mixed-methods evaluation (surveys, semistructured interviews and focus groups) of this initiative was focused on the ability of each jurisdiction to use synoptic reporting data to successfully implement and sustain QI projects to beyond the completion of the initiative and the lessons learnt in the process.

Successful treatment of hepatic oligometastases with stereotactic ablative radiotherapy and radiofrequency ablation in an anaplastic lymphoma kinase fusion-positive lung cancer patient.

Local ablative therapy with stereotactic ablative radiotherapy may improve survival in oncogene-addicted lung cancer patients with extracranial oligometastatic disease treated with targeted therapies. There is limited data on the use of radiofrequency ablation (RFA) in this same setting. We present a case of an anaplastic lymphoma kinase (ALK)-positive lung cancer patient with hepatic oligometastatic progression who was successfully treated with both stereotactic ablative radiation and RFA while continuing with an ALK inhibitor.

Synchronous metastatic seminoma and primary retroperitoneal ganglioneuroma: case report and literature review.

Testicular cancer is the most common malignancy in young men with seminomas comprising almost half of all germ cell tumours. Benign ganglioneuromas are rare tumours derived from the sympathetic nervous system. They usually occur in aldolescents and young adults and are predominantly located in the mediastinum and retroperitoneum.

Microchimerism in the rheumatoid nodules of patients with rheumatoid arthritis.

Objective: The rheumatoid nodule is a lesion commonly found on extraarticular areas prone to mechanic trauma. When present with inflammatory symmetric polyarthritis, it is pathognomonic of rheumatoid arthritis (RA), an autoimmune disease in which naturally acquired microchimerism has previously been described and can sometimes contribute to RA risk. Since RA patients harbor microchimerism in the blood, we hypothesized that microchimerism is also present in rheumatoid nodules and could play a role in rheumatoid nodule formation.

Tuberculosis of the bladder without previous renal infection.

Tuberculous (TB) infections are usually limited to the pulmonary system but the hematogenous spread of TB can result in secondary infections in any part of the body. Genitourinary TB is uncommon and follows hematogenous spread from a primary pulmonary infection to the kidneys. A rare case of a TB infection of the bladder without renal involvement is described.

Treatment of invasive breast carcinoma with ultrasound-guided radiofrequency ablation.

Background: Radiofrequency ablation (RFA) is a minimally invasive thermal ablation technique. This study reports the safety and efficacy of RFA as a minimally invasive strategy for breast cancers <3 cm diameter in postmenopausal women.

Methods: Twenty-two postmenopausal women (aged 60 years or older) with clinical T-1N0 core biopsy proven breast cancers were studied.
