Background: Some patients with non-small cell lung cancer (NSCLC) have superior short- and long-term outcomes with sleeve lobectomy rather than pneumonectomy. Originally sleeve lobectomy was reserved for patients with limited pulmonary function, however, the reported superior results allowed sleeve lobectomy to be performed in expanded patient populations. In a further attempt to improve post-operative outcomes surgeons have adopted minimally invasive techniques Minimally invasive approaches have potential benefits to patients such as decreased morbidity and mortality while maintaining the same caliber of oncologic outcomes.

The preferred radiotherapeutic approach for central (CLT) and ultracentral (UCLT) lung tumors is unclear. We assessed the toxicity and outcomes of patients with CLT and UCLT who underwent definitive five-fraction stereotactic body radiation therapy (SBRT). We reviewed the charts of patients with either CLT or UCLT managed with SBRT from June 2010-April 2019.

Article Synopsis
  • - The study focused on developing a novel optical surface applicator (OSA) for intraoperative photodynamic therapy (IO-PDT) to improve control over light distribution, which is important for tissue and tumor treatment.
  • - The OSA was made from flexible silicone with diffusing optical fibers, and its light distribution was tested both directly on the applicator and through tissue-simulating phantoms using a dosimetry system.
  • - Results showed improved uniformity of light distribution in phantoms compared to the OSA surface, and the OSA successfully delivered the intended light dose in a pilot study with swine, indicating its potential for effective therapy in clinical settings.

Background: Cancer registration provides data that can be utilized to study the etiology, diagnosis, prevention, and treatment of cancer. Despite the efforts of the World Health Organization (WHO), cancer registration is still underdeveloped in low- and middle-income countries (LMICs). This is the case in Lagos, Nigeria.

Objectives: Early stage lung cancer is being detected at a higher frequency with the implementation of screening programs. At the same time, medically complex patients with multiple comorbidities are presenting for surgery, with a concomitant rise in rates of sublobar resection. We sought to examine the effect of sampling lymph nodes on the outcomes of patients who undergo sublobar resection for small (<2 cm) stage I non-small cell lung cancer (NSCLC).

Background: As screening for lung cancer rises, an increase in the diagnosis of early stage lung cancers is expected. Lobectomy remains the standard treatment, but there are alternatives, consideration of which requires an estimation of the risk of surgery. Sarcopenia, irrespective of body mass index, confers a worse prognosis in many groups of patients including those undergoing surgery.

Objectives: Neoadjuvant therapy has emerged as a favoured treatment paradigm for patients with clinical N2 disease undergoing surgical resection for non-small-cell lung cancer. It is unclear whether such a treatment paradigm affects perioperative outcomes. We sought to examine the National Cancer Database (NCDB) to assess the impact of neoadjuvant therapy on perioperative outcomes and long-term survival in these patients.

Breast cancer is a major disease in Nigeria; in 2012, 27,304 new occurrences were diagnosed, and the number of mortalities was 13,960. Greater than 70% of patients present with advanced disease, which has a poor survival outcome. The mortality rates are high mainly because of a lack of awareness about breast health, screening guidelines, and treatment centers, and because of sociocultural barriers.

About 65% of cancer deaths globally occur in low to middle income countries (LMICs) where prioritization and allocation of resources to cancer care are often quite poor. In the absence of governmental focus on this problem, public-private partnerships may be an avenue to provide effective cancer control. This manuscript highlights the establishment of a nongovernmental organization (NGO) to stimulate the development of partnerships between oncology professionals, private enterprise, and academic institutions, both locally and internationally.

Introduction: We report a phase I trial of photodynamic therapy (PDT) of carcinoma in situ (CIS) and microinvasive cancer (MIC) of the central airways with the photosensitizer (PS) 2-[1-hexyloxyethyl]-2-devinyl pyropheophorbide-a (HPPH). HPPH has the advantage of minimal general phototoxicity over the commonly used photosensitizer porfimer sodium (Photofrin; Pinnacle Biologics, Chicago, IL).

Methods: The objectives of this study were (1) to determine the maximally tolerated light dose at a fixed photosensitizer dose and (2) to gain initial insight into the effectiveness of this treatment approach.

Photodynamic therapy (PDT) is an established treatment modality for non-small cell lung cancer. Phototoxicity, the primary adverse event, is expected to be minimized with the introduction of new photosensitizers that have shown promising results in phase I and II clinical studies. Early-stage and superficial endobronchial lesions less than 1 cm in thickness can be effectively treated with external light sources.
