Breast surgery for young women with early-stage breast cancer: Mastectomy or breast-conserving therapy?

Real-World Outcomes with the KEYNOTE-522 Regimen in Early-Stage Triple-Negative Breast Cancer

BACKGROUND

This study aimed to determine if the neoadjuvant (NAT) KEYNOTE-522 regimen was associated with higher rates of pathologic complete response (pCR), corresponding to higher rates of breast conservation therapy (BCT) in early-stage triple-negative breast cancer (TNBC) patients.

PATIENTS AND METHODS

Stage II-III TNBC patients diagnosed between 2019 and 2022 who underwent NAT were analyzed retrospectively. NAT with KEYNOTE-522 versus control NAT were compared for rates of BCT, axillary node dissection (ALND), pCR, and survival outcomes. The prevalence of immune-related adverse events (irAE) from chemoimmunotherapy was recorded.

RESULTS

Of 240 patients identified: 86 received KEYNOTE-522 and 154 received control. The frequency of pCR was significantly higher in KEYNOTE versus the control cohort, 59.3% and 33.1%, respectively (p = 0.001). There was no significant difference in the rate of BCT between the control (33.1%) and the KEYNOTE-522 (32.1%) groups (p = 0.47). Rates of ALND were significantly lower with KEYNOTE-522 (25.6%) as compared with control (39.6%); p = 0.03. The rate of development of grade 2 or higher irAEs was 34.9%. At a median follow-up of 2.4 years, there was no difference in survival outcomes. BRCA1 patients had high rates of pCR regardless of treatment group, KEYNOTE-522: 80.0% (4/5) and control: 75% (9/12), (p = 1).

CONCLUSION

This real-world evidence supports the use of the KEYNOTE-522 regimen in patients with early-stage TNBC given the higher pCR rate and corresponding decrease in the rate of ALND. The majority of patients in both NAT cohorts became BCT eligible, but the rate of BCT did not differ between the two groups.

Risk of first recurrence after treatment in a population-based cohort of young women with breast cancer

PURPOSE

Breast cancer (BC) in women under 45 is rare yet often aggressive. We aim to analyze loco-regional recurrences (LR), distant recurrences (DR), second breast cancers, and mortality in young BC patients.

METHODS

We enrolled 776 women with non-metastatic BC ≤45 years diagnosed from 1970 to 2012. Variables included age, family history, tumor stage/grade, and treatment. We used multivariate Cox regression and competing risk models.

RESULTS

Among the participants, 37.0% were diagnosed before the age of 40. Most had stage I or II, grade II, ER- and PR-positive, HER2-negative tumors. Over a median follow-up of 8.7 years, 10.1% experienced LR, 13.7% developed DR, and 10.8% died, primarily due to BC. The majority of recurrences occurred within the first five years. Older age (>40) significantly reduced the risk of LR and DR. Advanced disease stage, certain surgical strategies, and positive margins increased DR risk. In the cohort diagnosed between 2001 and 2012, recent diagnosis, triple-negative cancer, and hormonal therapy were associated with reduced LR risk. Breast-conserving surgery appeared to offer protective effects against DR.

CONCLUSION

This study highlights that BC in young women carries a significant risk of early recurrence, with age, tumor characteristics, and treatment modalities influencing outcomes. The findings emphasize the need for tailored treatment strategies for young BC patients, focusing on surgical precision and aggressive adjuvant therapy for high-risk cases. This research contributes valuable insights into managing BC in younger patients, aiding in improving long-term outcomes.

Young Women with Early-Stage Breast Cancer Treated with Upfront Surgery: Overview of Oncological Outcomes

Background: Breast cancer in young women aged < 40 years is rare and often aggressive with less favorable survival rates. The lack of systematic screening, later stage at diagnosis, and a more aggressive disease biology may all contribute to their poor prognosis. Data on the best management remain conflicting, especially those regarding surgical management, either breast-conserving or mastectomy. To our knowledge, there are limited studies surrounding the treatment of young women with early breast cancer, and this analysis evaluated the oncological outcomes for those patients who underwent surgery upfront. Methods: We conducted a retrospective study including 130 young women with early breast cancer from a total of 373 consecutive patients treated with upfront surgery between January 2016 and December 2021 at our institution. Local recurrence-free survival (LR-FS), distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS) were evaluated. Results: The median follow-up was 61.1 months (range, 25-95). A total of 92 (70.8%) patients underwent breast-conserving surgery, while 38 (29.2%) patients underwent conservative mastectomy with immediate implant breast reconstruction. In total, 8 of 130 patients (6.2%) developed a local recurrence in the treated breast, an7 (5.4%) patients presented distant metastasis. Overall, two (1.6%) patients died due to breast cancer recurrence. Conclusions: The results of our study interestingly support breast-conserving surgery in young patients with early-stage breast cancer. While appropriate breast-conserving surgery can achieve favorable oncological outcomes and can always be considered a valid alternative to conservative mastectomy in upfront surgery, a younger age at diagnosis should never be used alone to choose the type of surgery.

Impact of surgical types on overall survival in patients with ductal carcinoma in situ: an analysis based on the SEER database

Background

Breast cancer, as one of the most common malignancies among women globally, presents a concerning incidence rate, underscoring the importance of addressing the treatment of its precursor lesion, ductal carcinoma in situ (DCIS). Treatment decisions for DCIS, involving the balance between breast-conserving surgery (BCS) and mastectomy, remain an area requiring further investigation. This study aimed to compare influence of different surgical types on overall survival (OS) of patients with DCIS and identify specific subgroups with improved OS to develop an effective survival nomogram for patients.

Methods

Patient data from the Surveillance, Epidemiology, and End Results (SEER) database for DCIS cohort from 2010 to 2020 were retrieved. Kaplan-Meier (K-M) survival curves were utilized to compare prognostic OS of patients with different surgical methods. Cox regression analysis was employed to determine prognostic factors and establish a nomogram to predict 3-, 5-, and 10-year survival rates. The model was confirmed by Concordance Index (C-index), calibration curves, and receiver operating characteristic (ROC) curves.

Results

A total of 71,675 patients with DCIS were included. Patients who underwent subcutaneous mastectomy (SM) demonstrated the best OS compared to other surgical types. Additionally, adjuvant radiotherapy or chemotherapy in combination with surgery significantly improved OS compared to surgery alone. Among DCIS patients aged ≤74 years, those who underwent SM benefited the most in terms of OS, while in the age group of 63-74 years, patients who underwent BCS had significantly higher OS than those who underwent total (simple) mastectomy (TM)/modified radical mastectomy (MRM). Multiple factors were associated with improved OS in DCIS patients, and these factors were integrated into the nomogram to establish OS predictions. The C-index, calibration curves, and ROC curves indicated that the nomogram was suitable for assessing patient prognosis.

Conclusions

This study demonstrated that SM treatment yielded the best survival rates for DCIS patients, providing important guidance for future surgical decision-making. Moreover, identifying multiple independent factors related to survival and establishing reliable survival nomograms can assist physicians in developing personalized treatment plans and prolonging patient survival.

Frequency of use and characterization of frailty assessments in observational studies on older women with breast cancer: a systematic review

BACKGROUND

Breast cancer and frailty frequently co-occur in older women, and frailty status has been shown to predict negative health outcomes. However, the extent to which frailty assessments are utilized in observational research for the older breast cancer population is uncertain. Therefore, the aim of this review was to determine the frequency of use of frailty assessments in studies investigating survival or mortality, and characterize them, concentrating on literature from the past 5 years (2017-2022).

METHODS

MEDLINE, EMBASE and Cochrane Library were systematically queried to identify observational studies (case-control, cohort, cross-sectional) published from 2017-2022 that focus on older females (≥ 65 years) diagnosed with breast cancer, and which evaluate survival or mortality outcomes. Independent reviewers assessed the studies for eligibility using Covidence software. Extracted data included characteristics of each study as well as information on study design, study population, frailty assessments, and related health status assessments. Risk of bias was evaluated using the appropriate JBI tool. Information was cleaned, classified, and tabulated into review level summaries.

RESULTS

In total, 9823 studies were screened for inclusion. One-hundred and thirty studies were included in the final synthesis. Only 11 (8.5%) of these studies made use of a frailty assessment, of which 4 (3.1%) quantified frailty levels in their study population, at baseline. Characterization of frailty assessments demonstrated that there is a large variation in terms of frailty definitions and resulting patient classification (i.e., fit, pre-frail, frail). In the four studies that quantified frailty, the percentage of individuals classified as pre-frail and frail ranged from 18% to 29% and 0.7% to 21%, respectively. Identified frailty assessments included the Balducci score, the Geriatric 8 tool, the Adapted Searle Deficits Accumulation Frailty index, the Faurot Frailty index, and the Mian Deficits of Accumulation Frailty Index, among others. The Charlson Comorbidity Index was the most used alternative health status assessment, employed in 56.9% of all 130 studies. Surprisingly, 31.5% of all studies did not make use of any health status assessments.

CONCLUSION

Few observational studies examining mortality or survival outcomes in older women with breast cancer incorporate frailty assessments. Additionally, there is significant variation in definitions of frailty and classification of patients. While comorbidity assessments were more frequently included, the pivotal role of frailty for patient-centered decision-making in clinical practice, especially regarding treatment effectiveness and tolerance, necessitates more deliberate attention. Addressing this oversight more explicitly could enhance our ability to interpret observational research in older cancer patients.

Long-term oncologic outcomes following breast cancer surgery in adolescents and young adults: a single-center retrospective analysis

Background

Breast cancer (BC) in adolescents and young adults (AYAs, aged 15-39 years), remains inadequately understood. The incidence of BC in AYAs has been steadily increasing, making it the second leading cause of cancer-related mortality among females aged 0-39 globally. This study aimed to elucidate the clinical characteristics and long-term outcomes of AYAs and older adults (OAs, aged > 39 years) with BC who underwent surgery.

Methods

From January 2011 to June 2017, BC patients who underwent surgery were enrolled in this study and divided into AYA group and OA group. Clinical characteristics, recurrence-free survival (RFS), and overall survival (OS) were compared between these two groups, both before and after propensity score matching (PSM). Univariate and multivariate Cox proportional hazard regression analyses were performed to assess the influence of age on OS and RFS.

Results

Compared to the OA group, the AYA group exhibited a younger age at menarche (p < 0.001), a lower prevalence of menopausal status (p < 0.001), a reduced occurrence of comorbid conditions (p < 0.001), fewer instances of undergoing mastectomy (p = 0.031), a higher incidence of Triple-Negative Breast Cancer (TNBC) (p = 0.046), and elevated Ki-67 levels (p = 0.036). In terms of prognostic outcomes, within the study cohort, AYAs had a higher mortality rate and poorer long-term survival compared to OAs, both before and after PSM. In the PSM cohort, AYAs experienced a significantly shorter median OS (p < 0.001) and RFS (p < 0.001). Young age (15-39 years) emerged as an independent risk factor for OS (HR 2.659, 95% CI 1.385-5.106, p = 0.003) and RFS (HR 3.235, 95% CI 2.085-5.022, p < 0.001) in BC patients following surgery.

Conclusion

Significant differences were identified in the clinicopathological characteristics between AYA and OA patients with BC. In comparison to OA patients, AYA patients exhibited a less favorable long-term prognosis, with young age emerging as an independent prognostic risk factor for both OS and RFS in BC patients following surgery. Further investigations are warranted to develop age-specific therapeutic approaches for AYA BC patients.

Contemporary Review of the Management and Treatment of Young Breast Cancer Patients

Approximately 11% of all new breast cancer cases annually are diagnosed in young women, and this continues to be the leading cause of death in women age 20 to 49. Young, premenopausal breast cancer patients present with more advanced stages and with a higher proportion of aggressive subtypes such as triple negative and HER2-enriched tumors. Recently, the United States Preventive Services Task Force (USPSTF) lowered the age threshold to initiate screening mammograms to age 40 to aid in earlier detection. Young age at diagnosis increases the likelihood for a pathogenic mutation, and genetic testing is recommended for all patients age 50 and younger. This population is often underrepresented in landmark clinical trials, and data is extrapolated for the treatment of young women with breast cancer. Despite there being no survival benefit to more extensive surgical treatments, such as mastectomy or contralateral prophylactic mastectomy, many patients opt against breast conservation. Young patients with breast cancer face issues related to treatment toxicities, potential overtreatment of their disease, mental health, sexual health, and fertility preservation. This unique population requires a multidisciplinary care team of physicians, surgeons, genetic counselors, fertility specialists, mental health professionals, physical therapists, and dieticians to provide individualized, comprehensive care. Our aim is to (1) provide a narrative review of retrospective studies, relevant society guidelines, and clinical trials focused on the contemporary treatment and management of YBC patients and (2) discuss important nuances in their care as a guide for members of their multidisciplinary treatment team.

Overall survival after mastectomy versus breast-conserving surgery with adjuvant radiotherapy for early-stage breast cancer: meta-analysis

BACKGROUND

Breast-conserving surgery with adjuvant radiotherapy and mastectomy are currently offered as equivalent surgical options for early-stage breast cancer based on RCTs from the 1970s and 1980s. However, the treatment of breast cancer has evolved and recent observational studies suggest a survival advantage for breast-conserving surgery with adjuvant radiotherapy. A systematic review and meta-analysis was undertaken to summarize the contemporary evidence regarding survival after breast-conserving surgery with adjuvant radiotherapy versus mastectomy for women with early-stage breast cancer.

METHODS

A systematic search of MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL), and Embase that identified studies published between 1 January 2000 and 18 December 2023 comparing overall survival after breast-conserving surgery with adjuvant radiotherapy versus mastectomy for patients with unilateral stage 1-3 breast cancer was undertaken. The main exclusion criteria were studies evaluating neoadjuvant chemotherapy, rare breast cancer subtypes, and specific breast cancer populations. The ROBINS-I tool was used to assess risk of bias, with the overall certainty of evidence assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool. Studies without critical risk of bias were included in a quantitative meta-analysis.

RESULTS

From 11 750 abstracts, 108 eligible articles were identified, with one article including two studies; 29 studies were excluded from the meta-analysis due to an overall critical risk of bias, 42 studies were excluded due to overlapping study populations, and three studies were excluded due to reporting incompatible results. A total of 35 observational studies reported survival outcomes for 909 077 patients (362 390 patients undergoing mastectomy and 546 687 patients undergoing breast-conserving surgery with adjuvant radiotherapy). The pooled HR was 0.72 (95% c.i. 0.68 to 0.75, P < 0.001), demonstrating improved overall survival for patients undergoing breast-conserving surgery with adjuvant radiotherapy. The overall certainty of the evidence was very low.

CONCLUSION

This meta-analysis provides evidence suggesting a survival advantage for women undergoing breast-conserving surgery with adjuvant radiotherapy for early-stage breast cancer compared with mastectomy. Although these results should be interpreted with caution, they should be shared with patients to support informed surgical decision-making.

The factors involved in surgical decision-making in younger women diagnosed with breast cancer in Aotearoa New Zealand: A qualitative analysis

Women diagnosed with breast cancer must make important surgical decisions. The decision-making process for younger women is complex, with this group more likely to have an advanced diagnosis and life-stage considerations that can impact on treatment. This study investigated the decision-making process of women aged <50 years who had undergone breast cancer surgery within the preceding 12 months in Aotearoa New Zealand. Twelve women participated in semi-structured qualitative interviews to explore the factors that influenced treatment decisions. Thematic analysis resulted in three themes. Fear was the main concept identified as the primary influence on initial decision-making. Good quality shared decision-making between patient and clinician was found to provide essential support during the diagnosis to treatment period. In addition, women expressed a need for multi-modal presentation of medical information and more material reflecting younger women. These findings inform provision for younger women making surgical decisions when diagnosed with breast cancer.

Postoperative Radiotherapy Contributes to the Survival Benefit of Breast-Conserving Therapy over Mastectomy

Purpose

A survival benefit of breast-conserving therapy (BCT) over mastectomy has been shown in recent studies. This study aimed to explore differences in recurrence patterns between BCT and mastectomy and clarify the contribution of radiotherapy (RT) to the survival benefit of BCT.

Methods

Consecutive patients with pT1-2/pN0-1/M0 breast cancer between 2009 and 2015 in our institution were retrospectively reviewed and compared in matched cohorts using 1 : 1 propensity score matching (PSM).

Results

A total of 2370 patients were enrolled with a median follow-up of 75 (3-148) months. In the cohort without regional nodal irradiation (RNI), WBI was associated with significantly increased 10-year relapse-free survival (RFS), distant metastasis-free survival (DMFS), and regional recurrence-free survival (RRFS) compared with mastectomy alone. There were 419 pairs in the cohort without RNI and 87 pairs in the cohort with RNI after PSM. In the PSM cohort, improved 10-year RFS (95.4% vs. 82.7%, p < 0.05), DMFS (97.4% vs. 84.1%, p < 0.05), and RRFS (99.1% vs. 95.5%, p < 0.05) were observed in WBI compared with mastectomy alone. Regarding the first recurrence event, WBI demonstrated a significantly lower cumulative rate of distant metastases than mastectomy alone. There was no significant difference in survival outcomes between WBI plus RNI and PMRT before and after the PSM. In patients without RNI, mastectomy alone was significantly associated with unfavorable RFS (HR = 2.3, 95% CI 1.2-4.5, p < 0.05) and DMFS (HR = 2.5, 95% CI 1.1-5.8, p < 0.05).

Conclusion

This study found the benefit of RFS and DMFS in BCT patients compared with those treated with mastectomy without RNI but not in those treated with RNI. We hypothesized that RT played an important role in reducing the risk of regional recurrence and distant metastases.

Current Considerations in Surgical Treatment for Adolescents and Young Women with Breast Cancer

Adolescents and young women (AYA) with breast cancer represent a unique patient population, compared to the general population with breast cancer. We performed a literature review to evaluate the factors that influenced the surgical outcomes in this patient population. Fifty-two studies were identified, which evaluated breast surgery type, axillary surgery, contralateral prophylactic mastectomy (CPM), surgical timing, psychological factors, disparities, and imaging use. AYA patients had equivalent oncologic outcomes with breast conserving surgery (BCS) or mastectomy. CPM did not improve survival. There are limited data on axillary management in the AYA population, and while more data would be beneficial, this is currently extrapolated from the general breast cancer population. A shorter time to initiate treatment correlated to better outcomes, and disparities need to be overcome for optimal outcomes. AYA patients appreciated involvement in clinical decisions, and shared decision making should be considered whenever possible. Providers must keep these factors in mind when counseling AYA patients, regarding the surgical management of breast cancer.

Distance to radiation therapy facility influences surgery type among older women with early‐stage breast cancer

BACKGROUND

Breast-conserving surgery plus radiation (BCT) yields equivalent or better survival than mastectomy for early-stage breast cancer (ESBC) women. However, nationwide mastectomy trends increased in recent decades, attracting studies on underlying causes. Prior research identified that long distance to the radiation treatment facility (RTF) was associated with mastectomy. Still, it is unclear whether such association applies to young and old ESBC women comparably. We sought to delineate such impacts by age.

METHODS

Women diagnosed with stages 0-II breast cancer in 2013-2017 receiving either BCT or mastectomy were identified from the Louisiana Tumor Registry. We assessed the association of surgery (mastectomy vs. BCT) with the distance to the nearest or nearest accessible RTFs using multivariable logistic regression adjusting the socio-demographic and tumor characteristics. The nearest accessible RTF was determined based on patients' health insurance. For Medicaid, uninsured, and unknown insurance patients, the nearest accessible RTF is the nearest RTF owned by the government. The interaction effect of age and distance was evaluated as well.

RESULTS

Of 11,604 patients, 46.7% received mastectomy. Compared with distance ≤5 miles to the nearest RTF, those with distance ≥40 miles or 15-40 miles had higher odds of mastectomy (adjusted (adj) OR = 1.39, 95% CI = 1.07-1.82; adj OR = 1.17, 95% CI = 1.02-1.34). To the nearest accessible RTF, the adj ORs were 1.25 (95% CI = 1.03-1.51) and 1.19 (95% CI = 1.04-1.35), respectively. Age-stratified analysis showed the significant association (p < 0.05) only presented among women aged ≥65, but not those aged <65 years.

CONCLUSION

Distance to the nearest or nearest accessible RTF influences the surgery choice, especially among women in Louisiana ≥65 years with ESBC. Further understanding of factors leading to the decision for mastectomy in this age group is needed.

The Beneficial Impact of Intraoperative Ultrasound on Resection Margin Status during Breast Conserving Surgery

Background. Surgical resection with clear surgical cut margins is the mainstay of managing malignant breast neoplasms. Multiple techniques have been suggested to enhance resection status during breast-conserving surgery (BCS), including intraoperative ultrasonography (IOUS). Herein, we conducted the current investigation to reveal the benefit of IOUS on the achievement of R0 resection. Patients and Methods. This retrospective investigation included 140 patients who underwent BCS. They were divided into two groups: the IOUS group (40 cases) and the control group (100 cases). Our primary objective was to determine the free resection margin status (R0). Results. Both study groups expressed statistically comparable demographic and clinical data. Additionally, histopathological examination revealed no significant difference between the two groups regarding the tumor type, stage, or grade. Nonetheless, the R0 resection margin was more frequently encountered in association with IOUS application (97.5% compared to 79% in the control group), and that difference was statistically significant ( $p=0.007$ ). Conclusion. The application of IOUS has a significant beneficial impact on the outcomes of BCS. It is associated with a marked decline in positive resection margins, and its application should be encouraged in the breast oncological practice.

Patterns of care over 10 years in young breast cancer patients in the Netherlands, a nationwide population-based study

INTRODUCTION

Each year, around 600 young (<40 years) breast cancer (BC) patients are registered in the national NABON Breast Cancer Audit (NBCA). The aim of this study is to compare patient and treatment characteristics of young and older age BC patients over time with a focus on outcome of quality indicators (QIs). Furthermore, we analysed whether de-escalation trends of treatment can be recognized to the same degree in both patient groups.

MATERIAL AND METHODS

From October 2011 to October 2020 all patients treated for stage I-III invasive BC were included. Tumour characteristics, treatment variables and outcome of QIs of two age categories young (<40 years) and older patient (≥40 years) were analysed.

RESULTS

In total 114,700 patients were included: 4.6% young patients and 95.4% older patients. Young patients more often presented with a palpable mass, higher stage, and triple-negative BC. Overall, young patients more often started with neoadjuvant systemic treatment (NST) (54.3% vs. 18.6%) and a greater proportion of the young patients retained their breast contour after surgery (73.5% vs. 69.3%). De-escalation trends such as decrease in axillary lymph node dissections and in the use of boost were observed. The omission of radiation treatment after breast conserving surgery was only observed in older patients.

CONCLUSION

Although this study shows that young women more often present with unfavourable tumours, therapeutic procedures are performed with a higher adherence to the QIs than for older patients and young women do benefit from some de-escalation trends to the same extend as older patients.

A nomogram to identify appropriate candidates for breast-conserving surgery among young women with breast cancer: A large cohort study

Background

There is a gradual increase of female breast cancer under 35 years old, who was characterized as poor prognosis. Whether young patients could obtain greater survival benefits from breast-conserving surgery (BCS) than mastectomy remains controversial.

Methods

Breast cancer patients (≤35 years old) were selected from the Surveillance, Epidemiology, and End Results (SEER) database and divided into BCS and mastectomy group. Propensity score matching (PSM) was used to eliminate the distributional imbalance of variables among two groups. The influence of BCS on overall survival (OS) and breast cancer-specific survival (BCSS) was evaluated by Cox regression. Logistic regression was used to identify factors related to the benefit of BCS and to construct a nomogram. The nomogram was validated by the First Affiliated Hospital of Xi’an Jiaotong University cohort.

Results

Totally, 15,317 cases in the SEER database and 149 cases of external validation cohort were included. BCS was an independent protective factor for OS (P = 0.028) and BCSS (P = 0.042). A nomogram was established, and the AUC values both in the internal and external validation set were 0.780. The applicability of the model was verified in the PSM cohort and indicated that the survival advantage in the BCS-Benefit group was higher than that in the BCS-Nonbenefit and mastectomy group (P &lt;0.001).

Conclusions

For young breast cancer patients, BCS may bring better OS and BCSS than mastectomy, but not all benefit from it. We constructed a model for young patients (≤35 years old) that could identify appropriate candidates who benefit from BCS.

Analysis of the Rehabilitation Efficacy and Nutritional Status of Patients After Endoscopic Radical Thyroidectomy by Fast Track Surgery Based on Nutritional Support

Objective

To investigate and analyze the effect of fast track surgery (FTS) based on nutritional support on the improvement of rehabilitation efficacy and nutritional status of patients after radical lumpectomy for thyroid cancer.

Methods

Eighty-six patients admitted to our hospital for radical lumpectomy for thyroid cancer between April 2018 and April 2021 were selected, of which 40 patients admitted between April 2018 and April 2019 were included in the control group with conventional perioperative care. Forty-six patients admitted between May 2019 and April 2021 were included in the trial group with FTS care based on nutritional support. The two groups of patients were compared in terms of postoperative feeding time, length of stay, time out of bed, VAS scores, albumin (ALB), total protein (TP) and prealbumin (PA) levels, negative emotions [Mental Health Test Questionnaire (DCL-90)], quality of life [General Quality of Life Inventory (GQOLI-74)] and complication rates.

Results

The patients in the trial group had shorter feeding time, hospitalization time and time out of bed than the control group (P < 0.05). After the intervention, ALB, TP and PA levels were higher in the trial group than in the control group vs. preoperatively (P < 0.05); VAS scores in the trial group were lower than VAS scores in the control group during the same period (P < 0.05). The postoperative DCL-90 scores of the trial group were lower than those of the control group (P < 0.05); the GQOLI-74 scores and total scores of the trial group were higher than those of the control group at the 3-month postoperative follow-up (P < 0.05). The overall incidence of complications such as hoarseness, choking on water, hand and foot numbness, wound infection, and hypocalemia was lower in the trial group than in the control group (P < 0.05).

Conclusion

The implementation of FTS care based on nutritional support for patients after endoscopic radical thyroidectomyr can effectively improve the postoperative recovery and reduce their pain level, as well as help improve their nutritional status, negative emotions and improve their quality of life, which is worth promoting.

Breast-conserving therapy is associated with better survival than mastectomy in Early-stage breast cancer: A propensity score analysis

Background

Recent retrospective studies have reported that breast‐conserving therapy (BCT) led to improved overall survival (OS) than mastectomy in some populations. We aimed to compare the efficacy of BCT and mastectomy using the SEER database.

Materials and methods

Between 2010 and 2015, 99,790 eligible patients were identified. We included early‐stage breast cancer patients with 5cm or smaller tumors and three or fewer positive lymph nodes in our study. We compared the OS and breast cancer‐specific survival (BCSS) results among patients with BCT and those with mastectomy. Kaplan‐Meier plots, Cox proportional hazard regressions, competing risk analysis, and multivariate regressions were used to evaluate the outcomes. Propensity‐score matching was used to assemble a cohort of patients with similar baseline characteristics.

Results

In our study, 77,452 (77.6%) patients underwent BCT and 22,338 (22.4%) underwent mastectomy. The 5‐year OS rate was 94.7% in the BCT group and 87.6% in the mastectomy group, and the 5‐year BCSS was 97.2% in the BCT and 94.3% in the mastectomy group. Multivariate analysis in the matched cohort showed that women underwent mastectomy was associated with worse OS (Hazard ratio (HR) = 1.79; 95% confidence intervals (CIs) = 1.59–2.02, p < 0.001) and BCSS (HR = 1.88; 95% CIs = 1.61–2.18, p < 0.001) results compared with those underwent BCT. Patients with different subtypes and age group (>50 years old; ≤50 years old) received BCT showed significantly better OS and BCSS results than those received mastectomy. The effect of surgery choice on survival yielded similar results either for all patients or matched cohorts.

Conclusions

Our study showed that BCT was associated with improved survival compared with mastectomy in early‐stage breast cancer patients. It seems advisable to encourage patients to receive BCT rather than mastectomy in early‐stage patients when feasible and appropriate.
