Surgery is the oldest oncological discipline and remains the cornerstone of treatment for most patients with cancer. However, the way surgery is used to treat cancer has evolved and outcomes continue to improve as a result of greater biological understanding, relentless technical innovation and a paradigm shift towards multimodal treatment. In this Perspectives, the authors discuss the developments in cancer surgery that have occurred over time and provide an overview of the key uses of surgery in the current era of multidisciplinary cancer care. Surgery is the oldest oncological discipline, dating back thousands of years. Prior to the advent of anaesthesia and antisepsis 150 years ago, only the brave, desperate, or ill-advised patient underwent surgery because cure rates were low, and morbidity and mortality high. However, since then, cancer surgery has flourished, driven by relentless technical innovation and research. Historically, the mantra of the cancer surgeon was that increasingly radical surgery would enhance cure rates. The past 50 years have seen a paradigm shift, with the realization that multimodal therapy, technological advances, and minimally invasive techniques can reduce the need for, or the detrimental effects of, radical surgery. Preservation of form, function, and quality of life, without compromising survival, is the new mantra. Today's surgeons, no longer the uneducated technicians of history, are highly trained medical professionals and together with oncologists, radiologists, scientists, anaesthetists and nurses, have made cancer surgeries routine, safe, and highly effective. This article will review the major advances that have underpinned this evolution.

The risk of breast cancer in trans men is currently a poorly understood subject and trans men likely carries a different level of risk from that of cis women. This review aims to review several aspects that affects breast cancer risk in trans men and to apply the Swiss cheese model to highlight these risks. The study takes its cue from a systematic review of all described breast cancer cases in trans men following medical or surgical intervention because of gender dysphoria. PubMed was systematically searched on the 14th of March 2023 to find all published cases of breast cancer following chest contouring surgery in trans men. Included articles had to involve trans men, the diagnosis of breast cancer had to be preceded by either a medical or surgical intervention related to gender dysphoria, and cases needed to involve invasive breast cancer or ductal carcinoma in situ. Articles were excluded if gender identity in the case subject was unclear and/or a full English version of the report was unavailable. Quality and risk of bias was evaluated using the GRADE protocol. A literature review of specific risk altering aspects in this population followed. The Swiss cheese model was employed to present a risk analysis and to propose ways of managing this risk. 28 cases of breast cancer in trans men have been published. The Swiss cheese model identified several weaknesses associated with methods of preventing breast cancer in trans men. This study may highlight the difficulties with managing risk factors concerning breast cancer in trans men to clinicians not encountering this patient group frequently. This review finds that evidence for most aspects concerning breast cancer in trans men are inadequate, which supports the establishment of a risk-management approach to breast cancer in trans men.

To determine the predictive value of the \"Timed Up & Go\" (TUG), a validated assessment tool, on a prospective cohort study and to compare these findings to the ASA classification, an instrument commonly used for quantifying patients' physical status and anesthetic risk. In the onco-geriatric surgical population it is important to identify patients at increased risk of adverse post-operative outcome to minimize the risk of over- and under-treatment and improve outcome in this population. 280 patients ≥70 years undergoing elective surgery for solid tumors were prospectively recruited. Primary endpoint was 30-day morbidity. Pre-operatively TUG was administered and ASA-classification was registered. Data were analyzed using multivariable logistic regression analyses to estimate odds ratios (OR) and 95% confidence intervals (95%-CI). Absolute risks and area under the receiver operating characteristic curves (AUC's) were calculated. 180 (64.3%) patients (median age: 76) underwent major surgery. 55 (20.1%) patients experienced major complications. 50.0% of patients with high TUG and 25.6% of patients with ASA≥3 experienced major complications (absolute risks). TUG and ASA were independent predictors of the occurrence of major complications (TUG:OR 3.43; 95%-CI = 1.14-10.35. ASA1 vs. 2:OR 5.91; 95%-CI = 0.93-37.77. ASA1 vs. 3&4:OR 12.77; 95%-CI = 1.84-88.74). AUCTUG was 0.64 (95%-CI = 0.55-0.73, p = 0.001) and AUCASA was 0.59 (95%-CI = 0.51-0.67, p = 0.04). Twice as many onco-geriatric patients at risk of post-operative complications, who might benefit from pre-operative interventions, are identified using TUG than when using ASA.

There is a scarcity of data exploring the benefits of adjuvant or neoadjuvant chemotherapy in the treatment of breast cancer in older women. We aimed to explore the effect of adding chemotherapy to local therapy on overall survival in older women with triple-negative breast cancer. For this propensity-matched analysis, we used data from the National Cancer Database, a joint project of the Commission on Cancer of the American College of Surgeons and the American Cancer Society. We included data from women aged 70 years or older with surgically treated, American Joint Committee on Cancer (AJCC) Stage I–III invasive triple-negative breast cancer diagnosed from 2004 to 2014. Patients with T1aN0M0 disease and those with incomplete data on oestrogen receptor status, progesterone receptor status, or HER2 status were excluded. To reduce bias, patients were subdivided into three groups: those who were recommended chemotherapy but did not receive it; those who received chemotherapy; and those for whom chemotherapy was not recommended and not given. The primary outcome was overall survival. Multivariate Cox regression analysis and propensity score matching were done to minimise bias. Between Jan 1, 2004, and Dec, 31, 2014, 16 062 women with triple-negative breast cancer in the database met the inclusion criteria for this analysis. Median follow-up was 38·3 months (IQR 20·7–46·1, range 0–138·0; 95% CI 37·8–38·7). Collectively, the 5-year overall survival estimate of the 16 062 patients in the study cohort was 62·3% (95% CI 59·7–64·4). 5-year estimated overall survival was 68·5% (95% CI 66·4–70·6) for patients receiving chemotherapy, 61·1% (59·0–63·2) for patients recommended but not given chemotherapy, and 53·7% (51·8–55·8) for patients not recommended chemotherapy and not given chemotherapy (pooled log rank p<0·0001). Multivariate Cox regression analysis of a propensity score-matched sample comparing those who received chemotherapy with those who were recommended but not given chemotherapy (n=1884 matched pairs) identified improved overall survival with chemotherapy (hazard ratio [HR] 0·69 [95% CI 0·60–0·80]; p<0·0001). After stratifying the propensity score matching sample, this benefit persisted for node-negative women (HR 0·80 [95% CI 0·66–0·97]; p=0·007), node-positive women (0·76 [0·64–0·91]; p=0·006), and those with a comorbidity score greater than 0 (HR 0·74 [95% CI 0·59–0·94]; p=0·013). These data support consideration of chemotherapy in the treatment of women aged 70 years or older with triple-negative breast cancer. None.

Purpose The accurate harvesting of a sentinel node in breast cancer includes a sequence of procedures with components from different medical specialities, including nuclear medicine, radiology, surgical oncology and pathology. The aim of this document is to provide general information about sentinel lymph node detection in breast cancer patients. Methods The Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the European Association of Nuclear Medicine (EANM) have written and approved these guidelines to promote the use of nuclear medicine procedures with high quality. The final result has been discussed by distinguished experts from the EANM Oncology Committee, the SNMMI and the European Society of Surgical Oncology (ESSO). Conclusion The present guidelines for nuclear medicine practitioners offer assistance in optimizing the diagnostic information from the SLN procedure. These guidelines describe protocols currently used routinely, but do not include all existing procedures. They should therefore not be taken as exclusive of other nuclear medicine modalities that can be used to obtain comparable results. It is important to remember that the resources and facilities available for patient care may vary.

Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer mortality in women worldwide. Elderly individuals make up a large part of the breast cancer population, and there are important specific considerations for this population. The International Society of Geriatric Oncology created a task force to assess the available evidence on breast cancer in elderly individuals, and to provide evidence-based recommendations for the diagnosis and treatment of breast cancer in such individuals. A review of the published work was done with the results of a search on Medline for English-language articles published between 1990 and 2007 and of abstracts from key international conferences. Recommendations are given on the topics of screening, surgery, radiotherapy, (neo)adjuvant hormone treatment and chemotherapy, and metastatic disease. Since large randomised trials in elderly patients with breast cancer are scarce, there is little level I evidence for the treatment of such patients. The available evidence was reviewed and synthesised to provide consensus recommendations regarding the care of breast cancer in older adults.

Background When ipsilateral multifocal primary breast cancer (IMBC) is detected, standard routine is to evaluate the largest tumor with immunohistochemistry (IHC). As all foci are not routinely characterized, many patients may not receive optimal adjuvant treatment. Here, we assess the clinical relevance of examining at least two foci present in patients with IMBC. Methods Patients diagnosed and treated for IMBC at Sahlgrenska University Hospital (Gothenburg, Sweden) between 2012 and 2017 were screened. In total, 180 patients with ≥ 2 invasive foci (183 specimens) were assessed with IHC and included in this study. Expression of the estrogen (ER) and progesterone (PR) receptors, Ki67, HER2, and tumor grade were used to determine the molecular surrogate subtypes and discordance among the foci was recorded. An additional multidisciplinary team board was then held to re-assess whether treatment recommendations changed due to discordances in molecular surrogate subtype between the different foci. Results Discordance in ER, PR, HER2, and Ki67 was found in 2.7%, 19.1%, 7.7%, and 16.9% of invasive foci, respectively. Discordance in the molecular surrogate subtypes was found in 48 of 180 (26.7%) patients, which resulted in therapy changes for 11 patients (6.1%). These patients received additional endocrine therapy ( n  = 2), chemotherapy ( n  = 3), and combined chemotherapy and trastuzumab ( n  = 6). Conclusion Taken together, when assessing at least two tumor foci with IHC, regardless of shared morphology or tumor grade between the different foci, 6.1% of patients with IMBC were recommended additional adjuvant treatment. A pathologic assessment using IHC of all foci is therefore recommended to assist in individualized treatment decision making.

Background Routine clinical management of breast cancer (BC) currently depends on surrogate subtypes according to estrogen- (ER) and progesterone (PR) receptor, Ki-67, and HER2-status. However, there has been growing demand for reduced immunohistochemistry (IHC) turnaround times. The Xpert® Breast Cancer STRAT4* Assay (STRAT4)*, a standardized test for ESR1 / PGR / MKi67 / ERBB2 mRNA biomarker assessment, takes less than 2 hours. Here, we compared the concordance between the STRAT4 and IHC/SISH, thereby evaluating the effect of method choice on surrogate subtype assessment and adjuvant treatment decisions. Methods In total, 100 formalin-fixed paraffin-embedded core needle biopsy (CNB) samples and matching surgical specimens for 98 patients with primary invasive BC were evaluated using the STRAT4 assay. The concordance between STRAT4 and IHC was calculated for individual markers for the CNB and surgical specimens. In addition, we investigated whether changes in surrogate BC subtyping based on the STRAT4 results would change adjuvant treatment recommendations. Results The overall percent agreement (OPA) between STRAT4 and IHC/SISH ranged between 76 and 99% for the different biomarkers. Concordance for all four biomarkers in the surgical specimens and CNBs was only 66 and 57%, respectively. In total, 74% of surgical specimens were concordant for subtype, regardless of the method used. IHC- and STRAT4-based subtyping for the surgical specimen were shown to be discordant for 25/98 patients and 18/25 patients would theoretically have been recommended a different adjuvant treatment, primarily receiving more chemotherapy and trastuzumab. Conclusions A comparison of data from IHC/in situ hybridization and STRAT4 demonstrated that subsequent changes in surrogate subtyping for the surgical specimen may theoretically result in more adjuvant treatment given, primarily with chemotherapy and trastuzumab.

Background Physical performance tests are a reflection of health in older adults. The Timed Up and Go test is an easy-to-administer tool measuring physical performance. In older adults undergoing oncologic surgery, an impaired TUG has been associated with higher rates of postoperative complications and increased short term mortality. The objective of this study is to investigate the association between physical performance and long term outcomes. Methods Patients aged ≥65 years undergoing surgery for solid tumors in three prospective cohort studies, ‘PICNIC’, ‘PICNIC B-HAPPY’ and ‘PREOP’, were included. The TUG was administered 2 weeks before surgery, a score of ≥12 seconds was considered to be impaired. Primary endpoint was 5-year survival, secondary endpoint was 30-day major complications. Survival proportions were estimated using Kaplan-Meier curves. Cox- and logistic regression analysis were used for survival and complications respectively. Hazard ratios (aHRs) and Odds ratios (aOR) were adjusted for literature-based and clinically relevant variables, and 95% confidence intervals (95% CIs) were estimated using multivariable models. Results In total, 528 patients were included into analysis. Mean age was 75 years (SD 5.98), in 123 (23.3%) patients, the TUG was impaired. Five-year survival proportions were 0.56 and 0.49 for patients with normal TUG and impaired TUG respectively. An impaired TUG was an independent predictor of increased 5-year mortality (aHR 1.43, 95% CI 1.02-2.02). The TUG was not a significant predictor of 30-day major complications (aOR 1.46, 95% CI 0.70-3.06). Conclusions An impaired TUG is associated with increased 5-year mortality in older adults undergoing surgery for solid tumors. It requires further investigation whether an impaired TUG can be reversed and thus improve long-term outcomes.

Age is the most important risk factor for the occurrence of cancer, and a declining mortality from heart disease and other non-cancer causes leaves an older population that is at high risk of developing cancer. Choosing the optimal treatment for older cancer patients may be a challenge. Firstly, older age and associated factors such as comorbidities, functional limitations, and cognitive impairment are risk factors for adverse effects of cancer treatment. Secondly, older patients are often excluded from clinical trials, and current clinical guidelines rarely address how to manage cancer in patients who have comorbidities or functional limitations. The importance of incorporating frailty assessment into the preoperative evaluation of older surgical patients has received increasing attention over the last 10 years. Furthermore, studies that include endpoints such as functional status, cognitive status, and quality of life beyond the standard endpoints, i.e. postoperative morbidity and mortality, are starting to emerge. This review looks at recent evidence regarding geriatric assessment and frailty in older surgical cancer patients and provides a summary of newer studies in colorectal, liver, pancreatic, and gynecological cancer and renal and central nervous system tumors.
