Purpose: Randomized trials have demonstrated similar local tumor control in patients treated with accelerated partial-breast irradiation (APBI) compared with whole-breast irradiation. However, the optimal APBI dose for maximizing tumor control and minimizing toxicity is uncertain.

Methods And Materials: We enrolled patients ≥18 years of age with grade 1 or 2 ductal carcinoma in situ or stage I invasive breast cancer and resection margins ≥2 mm between 2003 and 2011 to a sequential dose-escalation trial using 3-dimensional conformal external beam APBI giving twice daily 4 Gy fractions with total doses of 32 Gy, 36 Gy, and 40 Gy.

Background: Nipple-sparing mastectomy (NSM) is infrequently performed in older women, at least in part owing to concerns regarding age-related complications. We describe postoperative outcomes of NSM in older women and risk factors for complications, with the goal of informing patient selection and decision-making.

Patients And Methods: Cases of NSM with immediate implant-based reconstruction were identified from an institutional database (2009-2019).

Introduction: Triphallia, a rare congenital anomaly describing the presence of three distinct penile shafts, has been reported only once in the literature. This case report, based on an extensive literature review, describes the serendipitous discovery during cadaveric dissection of the second reported human case of triphallia, distinctly morphologically different from the previous case.

Case Presentation: Despite the normal appearance of external genitalia on examination, the dissection of a 78-year-old white male revealed a remarkable anatomical variation: two small supernumerary penises stacked in a sagittal orientation posteroinferiorly to the primary penis.

Background: Axillary recurrence following lumpectomy with a negative sentinel lymph node biopsy (SLNB) is rare, possibly due to routine use of whole breast radiation. In this study, we characterized the rate of any axillary recurrence among mastectomy patients with a negative SLNB and no adjuvant radiation therapy.

Methods: We identified women who underwent mastectomy with SLNB for early-stage breast cancer (1999-2005) and included patients with pathologically negative nodes and no axillary dissection or adjuvant radiation.

Article Synopsis
  • There is a significant challenge with treating relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL) using existing CAR T-cell therapies, particularly as there are no approved options for CLL patients.
  • This study focuses on a new CAR design targeting the B-cell activating factor receptor (BAFF-R), which is crucial for the survival of B-cells and commonly found on CLL tumors.
  • The research showed that BAFF-R CAR T cells are effective in killing CLL cells and can also target resistant CD19-knockout CLL cells, suggesting that this therapy could provide a much-needed treatment option for CLL patients.

Article Synopsis
  • - New therapies have boosted survival rates for chronic lymphocytic leukemia (CLL), but high-risk patients still face challenges with treatment failure.
  • - Allogeneic hematopoietic cell transplantation (allo-HCT) was once the main treatment for high-risk CLL, but targeted therapies like BTK and BCL-2 inhibitors have shifted its use to later stages of the disease.
  • - Chimeric antigen receptor T-cell (CAR T) therapies show promise for treating relapsed/refractory CLL, particularly for patients who did not respond to prior treatments, although no CAR T therapies have yet been approved specifically for CLL.

Background: Nipple-sparing mastectomy (NSM) is an oncologically safe approach for breast cancer treatment and prevention; however, there are little long-term data to guide management for patients whose nipple margins contain tumor or atypia.

Methods: NSM patients with tumor or atypia in their nipple margin were identified from a prospectively maintained, single-institution database of consecutive NSMs. Patient and tumor characteristics, treatment, recurrence, and survival data were assessed.

Patients with chronic pain have a higher prevalence of mood disorders with depression and anxiety contributing to higher pain intensity, emotional allodynia, and neuro-anatomical changes. We sought to quantify the prevalence of psychiatric comorbidities (PCs) in a tertiary referral clinic for temporomandibular disorders (TMDs). Medical records of all patients attending clinics run by three tertiary temporomandibular joint (TMJ) surgeons for the period January to April 2022 inclusive were audited for the prevalence of concomitant psychiatric conditions.

Article Synopsis
  • Lumpectomy and mastectomy have similar survival rates for breast cancer patients, but incomplete tumor removal indicated by positive lumpectomy margins can lead to local recurrence and increased mortality, often requiring a second surgery.
  • A clinical trial was conducted to determine the effectiveness of pegulicianine fluorescence-guided surgery (pFGS) in identifying cancerous margins during lumpectomy for various breast cancer stages, where patients were randomly assigned to pFGS or control groups to evaluate margin status.
  • Results showed that pFGS successfully identified residual tumors in some cases, avoiding second surgeries for some patients with positive margins; however, the overall sensitivity of pFGS was lower than hoped despite meeting specificity and successfully removing some remaining cancer.

Several CD19-targeting CAR-T cells are used to treat leukemias and lymphomas; however, relapsed and/or refractory (R/R) disease is still observed in a significant number of patients. Additionally, the success of CD19-CAR-T cell therapies is not uniform across hematological malignancies, particularly in chronic lymphocytic leukemia (CLL). In this study, we present the development of a novel CAR-T cell therapy targeting B-cell activating factor receptor (BAFF-R), a key regulator of B-cell proliferation and maturation.

Article Synopsis
  • The study aimed to assess whether the time it takes for patients to undergo surgery based on their race can serve as an indicator of health equity in access to surgical care.
  • Using data from the National Cancer Database involving nearly 887,000 women with stage I-III breast cancer, the research found that Black patients were significantly more likely to experience surgery delays compared to White patients.
  • The findings underscore the need to address systemic factors contributing to this inequity in cancer treatment, suggesting that timely surgery access for Black patients should be a priority for intervention efforts.

Background: Retention of the nipple-areola complex with nipple-sparing mastectomy (NSM) techniques provides a more natural cosmetic result than procedures that sacrifice the nipple. While the oncologic safety of NSM is established by several studies, there is little long-term data on outcomes in BRCA mutation carriers with breast cancer.

Patients And Methods: BRCA1/2 mutation carriers who underwent NSM and immediate reconstruction from 2008 to 2019 were reviewed and patients with breast cancer on biopsy or final pathology were included.

Chimeric antigen receptors (CARs) are synthetic engineered receptors with an antigen recognition domain derived from a high-specificity monoclonal antibody that can target surface molecules on tumor cells. T cells are genetically engineered to express CARs, thereby harnessing the antigen-recognition ability of antibodies and effector function of T cells. Target surface molecule selection is crucial for manufacturing CARs.

Background: Despite promising pilot study results, adoption of neurotization of immediate implant-based reconstructions has not occurred.

Methods: For surgeons interested in adopting breast reinnervation techniques, we present ways to overcome initial barriers by decreasing operative time and maximizing chances of sensory recovery.

Results: We discuss the combined experience at two academic teaching hospitals, where neurotization of both immediate tissue expander cases and direct-to-implant reconstructions are performed through varying mastectomy incisions.

Background: The prevalence of same-day mastectomy with reconstruction has continued to increase across the United States in recent years. Prior studies have shown that same-day mastectomy with reconstruction leads to increased patient satisfaction and allows hospitals to use resources better. This study sought to evaluate the implementation of same-day mastectomy with a reconstruction recovery protocol for patients undergoing mastectomy at our institution.

The Ser/Thr protein kinase Wee1 plays a regulatory role at the G/M checkpoint by phosphorylating CDK1 when DNA is damaged to allow time for DNA to repair, disruption of which is a key approach to sensitise cancer cells to DNA-damaging therapies. The main selective inhibitor for Wee1 undergoing development in clinical trials, AZD1775, however, has been shown to have off target effects towards other protein kinases with similar potency. Here we describe the synthesis and assessment of a series of Wee1-degrading PROTACs using AZD1775 linked to either the VHL ligand VH032 or to the CRBN ligand pomalidomide using different types and lengths of linkers.

Chronic lymphocytic leukemia (CLL) is the most prevalent leukemia in the Western hemisphere. The recent availability of novel targeted therapies, namely Bruton's tyrosine kinase, phosphoinositide-3 kinase, and BCL-2 inhibitors, have revolutionized the treatment algorithm for CLL but have not yet resulted in cure. Advances in the field of immuno-oncology and T cell engineering brought chimeric antigen receptor (CAR) T cell therapy from the laboratory to the clinic for treatment of B cell lymphoid malignancies and has improved the disease response and survival outcomes of various types of relapsed and/or refractory B cell lymphomas.
