American Cancer Society lung cancer screening guidelines.

Findings from the National Cancer Institute's National Lung Screening Trial established that lung cancer mortality in specific high-risk groups can be reduced by annual screening with low-dose computed tomography. These findings indicate that the adoption of lung cancer screening could save many lives. Based on the results of the National Lung Screening Trial, the American Cancer Society is issuing an initial guideline for lung cancer screening. This guideline recommends that clinicians with access to high-volume, high-quality lung cancer screening and treatment centers should initiate a discussion about screening with apparently healthy patients aged 55 years to 74 years who have at least a 30-pack-year smoking history and who currently smoke or have quit within the past 15 years. A process of informed and shared decision-making with a clinician related to the potential benefits, limitations, and harms associated with screening for lung cancer with low-dose computed tomography should occur before any decision is made to initiate lung cancer screening. Smoking cessation counseling remains a high priority for clinical attention in discussions with current smokers, who should be informed of their continuing risk of lung cancer. Screening should not be viewed as an alternative to smoking cessation.

Are we Overtreating Hormone Receptor Positive Breast Cancer with Neoadjuvant Chemotherapy? Role of OncotypeDx® for Hormone Receptor Positive Patients Undergoing Neoadjuvant Chemotherapy.

BACKGROUND: The utilization of OncotypeDx in the setting of neoadjuvant chemotherapy (NCT) is not well defined. The objective of this study was to determine what proportion of hormone receptor (HR)-positive patients undergoing NCT would not benefit from chemotherapy based on OncotypeDx recurrence scores (RS) and predictors of a high RS as defined by the TAILORx trial. METHODS: The National Cancer Data Base was used to identify patients with unilateral clinical stage I-III HR+/Her2- breast cancer who had an OncotypeDx score and who had undergone NCT. Patients undergoing adjuvant chemotherapy were used as a comparison group. RESULTS: Of 307,666 patients, 41.8% had testing with OncotypeDx. Of these, 76.6% had no chemotherapy, 22.3% adjuvant chemotherapy, and 1.1% NCT. OncotypeDx testing in NCT patients increased from 4.9% in 2010 to 8.2% in 2015. Of NCT patients with OncotypeDx testing, 11.6% had RS < 11, 44.4% RS 11-25, and 43.9% RS > 25. In patients age ≤ 50 years, 14.5% had RS < 11, 12.4% RS 11-15, 31.4% RS 16-25, and 41.7% RS > 25. Predictors of RS > 25 on multivariable analysis included grade 3 tumors (odds ratio [OR] 3.83) and PR-negative tumors (OR 5.26) but not clinical T or N stage (p > 0.05). CONCLUSIONS: More than half of patients with OncotypeDx testing are being overtreated with NCT, and a third of younger patients are being overtreated. Predictors of a high RS are reliably available at core biopsy, suggesting an application of OncotypeDx in determining the need for NCT for some HR-positive breast cancers.

An In-Visit Decision Aid for Surgeons to Address Decision Making for Bilateral Mastectomy for Newly Diagnosed Breast Cancer Patients.

BACKGROUND: Few decision aids for newly diagnosed breast cancer patients are used by surgeons during their consultations with patients. METHODS: From 2017 to 2019, an online interactive breast cancer in-visit decision aid (BIDA) was used on 63 patients and 57 patients underwent usual care (UC). We compared knowledge, decision involvement, anxiety and distress (HADS scale), quality of life (PROMIS), fear of recurrence, body image, and patient values between BIDA and UC before surgery. A knowledge score of ≥ 57% was considered "high knowledge." RESULTS: A total of 188 patients were enrolled of which 120 (63.8%) completed all study procedures. Patient demographic characteristics and anxiety and quality of life (QOL) at baseline were similar between patients in BIDA and UC cohorts. After seeing the surgeon, patients in the BIDA group had higher composite knowledge scores compared with UC patients [n = 55 (87.3%) vs. n = 39 (68.4%) respectively, p = 0.012]. Patients in the BIDA cohort reported being asked more often their surgical preference (p = 0.013) and discussing bilateral mastectomy (BM) as an option (p = 0.048). There was a trend of less patients in the BIDA cohort undergoing BM then in the UC cohort [10 (15.9%) vs. 14 (24.6%), p = 0.49]. Anxiety and distress, QOL, fear of recurrence, and body image were not significantly different between BIDA and UC cohorts. CONCLUSIONS: A decision aid used by surgeons during their consultation was associated with higher knowledge levels, patients reporting more discussion about BM, and a trend of lower BMs. A larger study with more patients is needed to confirm this finding.

Axillary Surgery for Early-Stage, Node-Positive Mastectomy Patients and the Use of Postmastectomy Chest Wall Radiation Therapy.

BACKGROUND: We examined axillary surgery in mastectomy patients with tumor-positive nodes and how the type of axillary surgery impacted use of postmastectomy chest wall radiation therapy (PMRT). METHODS: Using the National Cancer Data Base, we selected patients with AJCC cT1/T2c N0 breast cancer with one to three tumor-positive lymph nodes treated between 2013 and 2014. Type of axillary surgery was analyzed using the FORDS scope of regional lymph node surgery variable. Multivariable logistic regression modeling was used to identify independent predictors associated with SNB alone and the use of PMRT. RESULTS: Of 8089 patients, 2482 (30.7%) underwent SNB alone, 1339 (16.6%) underwent axillary dissection (ALND) alone, and 4268 (52.7%) underwent SNB followed by ALND. Fifty-seven percent of patients with micrometastases underwent SNB alone compared with 22.6% of patients with macrometastases. Independent predictors of SNB alone for patients with micrometastases were African American race, number of nodes positive, and PMRT. For patients with macrometastases, age, facility type and location, and PMRT were independent predictors for SNB alone. Of 2449 patients who underwent SNB alone, 1538 (62.8%) had no PMRT, 261 (10.7%) had PMRT alone, and 650 (26.5%) had PMRT with regional nodal irradiation. Patients undergoing SNB alone were 1.70 times [96% confidence interval (CI) 1.45-2.00] more likely to undergo PMRT than upfront ALND and 1.51 times (96% CI 1.34-1.71) more likely than SNB followed by ALND. CONCLUSIONS: Surgeons are omitting completion ALND in a third of early-stage, node-positive mastectomy patients. SNB alone patients are more likely to undergo PMRT than patients undergoing ALND.

Impact of an In-visit Decision Aid on Patient Knowledge about Contralateral Prophylactic Mastectomy: A Pilot Study.

BACKGROUND: Studies have reported that breast cancer patients have limited understanding about the oncologic outcomes following contralateral prophylactic mastectomy (CPM). We hypothesized that an in-visit decision aid (DA) would be associated with higher patient knowledge about the anticipated short and long term outcomes of CPM. METHODS: We piloted a DA which used the SCOPED: (Situation, Choices, Objectives, People, Evaluation and Decision) framework. Knowledge, dichotomized as "low" (≤3 correct) versus "high" (≥4 correct), was assessed immediately after the visit by a 5 item survey. There were 97 DA patients (response rate 62.2 %) and 114 usual care (UC) patients (response rate 71.3 %). RESULTS: Patient demographic factors were similar between the two groups. Twenty-one (21.7 %) patients in the DA group underwent CPM compared with 18 (15.8 %) in the UC group (p = 0.22). Mean and median knowledge levels were significantly higher in the DA group compared with the UC group for patients of all ages, tumor stage, race, family history, anxiety levels, worry about CBC, and surgery type. Eighty-six (78.9 %) of UC versus 35 (37.9 %) DA patients had low knowledge. Of patients who underwent CPM, 15 (83.3 %) in the UC cohort versus 5 (25.0 %) of DA patients had "low" knowledge. CONCLUSIONS: Knowledge was higher in the DA group. The UC group had approximately three times the number of patients of the DA group who were at risk for making a poorly informed decision to have CPM. Future studies should assess the impact of increased knowledge on overall CPM rates.

Long-term patterns and predictors of pain following laparoscopic inguinal hernia repair: a patient-centered analysis.

BACKGROUND: Laparoscopic inguinal hernia repair has been shown to offer patients the benefit of less postoperative pain as compared to traditional open techniques. However, the risk of experiencing significant postoperative pain may affect patient's decision making. We aimed to elucidate potential patterns of pain and the predictors of such, up to 2 years postoperatively, using both generic and specific quality of life tools. METHODS: Patients undergoing laparoscopic totally extra-peritoneal inguinal hernia repair were identified from a prospectively maintained database. Short form-36, Surgical Outcomes Measurement System (SOMS) and Carolinas Comfort Scale (CCS) surveys were administered pre- and postoperatively at 3 weeks, 6 months, 1 and 2 years. Patients with concomitant procedures were excluded. Significant pain was considered mild but bothersome or worse on either specific tool (SOMS scores ≥3/4, CCS scores ≥2). Predictors of significant pain were determined by logistic regression. RESULTS: From 2009 to 2015, 482 patients enrolled in our database underwent elective TEP repair of 626 hernias and completed an assessment tool. Mean age was 57 (±15) years, with 93 % male. Reported pain on all three tools improved significantly from baseline over time (p < 0.01). Significant pain on either specific tool, related or unrelated to surgery, was reported by 52 % of respondents (158/301) preoperatively, and postoperatively by 50 % at 3 weeks (111/220), 21 % at 6 months (15/70), 13 % at 1 year (14/108), and 25 % at 2 years (30/121). Significant pain at 6 months-2 years correlated more significantly with general health status than surgical factors. CONCLUSIONS: Significant pain can be as high as 50 % at 3 weeks on surgery-specific quality of life measures, but with significant improvement by 6 months which is maintained through 2 years. Poor quality of life and general health were the main predictors of pain after 6 months.

Patient satisfaction with nipple-sparing mastectomy: A prospective study of patient reported outcomes using the BREAST-Q.

BACKGROUND AND OBJECTIVES: The authors sought to study patient-reported outcomes following nipple-sparing mastectomy (NSM). METHODS: From 2008 to 2011, the BREAST-Q was administered to women undergoing NSM surgery for cancer treatment or risk-reduction prior to surgery and at 2 years after completion of reconstruction. The change in score over time and the impact of surgical indication, complication occurrence, and laterality on scores were analyzed. RESULTS: The BREAST-Q was prospectively administered to 39 women undergoing NSM for cancer treatment (n = 17) or risk-reduction (RR) (n = 22). At 2 years after operation, median overall satisfaction with breasts was 75 (IQR = 67,100). There were significant postoperative increases in scores for overall satisfaction with breasts (+8, P = 0.021) and psychosocial well-being (+14, P = 0.003). Postoperatively, RR patients had significantly higher scores for psychosocial wellness, physical impact (chest), and overall satisfaction with outcome compared to cancer treatment patients (P < 0.05). Also, increase from preoperative to postoperative psychosocial wellness was higher in the RR compared to cancer treatment patients (+17 vs. +1, P = 0.043). Complication occurrence did not significantly impact postoperative scores. CONCLUSIONS: Following NSM for cancer treatment or RR, patients demonstrated high levels of satisfaction and quality of life as measured by BREAST-Q. Satisfaction level increased 2 years following operation. J. Surg. Oncol. 2016;114:416-422. © 2016 Wiley Periodicals, Inc.

Patient-centered outcomes following laparoscopic inguinal hernia repair.

BACKGROUND: Inguinal hernia repair is the most common surgery in the world. Health-related quality of life (HRQOL) outcomes are arguably the most important elements of successful repair. This study is aimed to describe short- and long-term quality of life outcomes in patients undergoing laparoscopic inguinal hernia repair. METHODS: We prospectively followed patients who underwent totally extraperitoneal laparoscopic inguinal hernia repair (TEP) as part of an Institutional Review Board-approved study. HRQOL was measured preoperatively, or 3 weeks, 6 months, and 1 year postoperatively using Short Form 36 Health Survey Version 2 (SF-36v2) and Carolinas Comfort Scale. Postoperative HRQOL scores were compared to baseline using paired t tests. RESULTS: Between June 2009 and February 2014, 1,175 patients underwent TEP by four surgeons. Of those, 301 patients with 388 hernias were registered in the database and followed by a research coordinator. Mean age was 56.4 ± 15.2 years and 93% were male. Mean body mass index was 26.1 ± 3.7 kg/m(2). Seventy-eight percent presented with pain, the majority of which were described as mild. Hernias were unilateral right-sided in 43%, left-sided in 28%, and bilateral in 29 %. Eighty-five percent were primary hernias. Average operative time was 43.5 ± 17.9 min and there were no intraoperative complications. Urinary retention occurred in 6%. Visual analog scale at discharge was 1.9 ± 1.7. Analgesics were used an average of 2.5 ± 3.4 days and return to activities of daily living and work occurred on postoperative 5.5 ± 4.4 and 5.6 ± 3.9 days. Recurrence occurred in 2.1%. Significant improvements between baseline and 1 year were found in role limitations due to physical health (81.5 ± 25.6 vs. 91.8 ± 19.4, p = 0.02), social functioning (87.4 ± 21.3 vs. 92.9 ± 15.3, p = 0.02), and pain (78.2 ± 19.7 vs. 86.6 ± 15.9, p = 0.007). CONCLUSIONS: TEP results in significant improvement in HRQOL including physical health, social functioning, and pain at 1 year. On average, patients are able to return to activities of daily living and work within a week.

Endoscopic treatment for Bouveret syndrome.

BACKGROUND: Gallstone ileus is an uncommon cause for small bowel obstruction. Less than 3 % of cases are due to a gallstone impacted in the duodenum or pylorus resulting in a gastric outlet obstruction, described by Bouveret in 1896. Most of the successful therapeutic maneuvers described involve open surgical removal of the stone through either a gastrotomy or duodenotomy, and reported morbidity is not insignificant. Endoscopic techniques continue to evolve, allowing for more complex procedures and avoidance of open surgery and its accompanying high morbidity. This video displays a rarely used endoscopic method of relieving gastric outlet obstruction caused by a stone in a patient with Bouveret syndrome. METHODS: Video of successful endoscopic retrieval of a gallstone lodged in the pylorus is presented. An endoscopic retrieval basket is used, and key maneuvers highlighted include passage of the closed device distal to the stone, opening of the basket, and withdrawal of the stone under direct vision. RESULTS: After successful retrieval, endoscopic inspection revealed a normal duodenum and relief of the obstruction. Cholecystectomy was not performed, given that most cholecystoduodenal fistulae are large and will spontaneously close, especially if a patent cystic duct is present. Liver function tests were normal postoperatively, so no further evaluation of the bile duct was necessary. CONCLUSIONS: With new advances in technology, the endoscopic approach should be considered as the first line of treatment for cases of Bouveret syndrome because most patients are elderly with multiple comorbidities.

Patient-centered outcomes after laparoscopic cholecystectomy.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the second most common general surgical operation performed in the United States, yet little has been reported on patient-centered outcomes. METHODS: We prospectively followed 100 patients for 2 years as part of an institutional review board-approved study. The Surgical Outcomes Measurement System (SOMS) was used to quantify quality-of-life (QoL) values at various time points postoperatively. RESULTS: Maximum pain was reported at 24 h (5.5 ± 2.2), and decreased to preoperative levels at 7 days (1.2 ± 2.3 vs. 2.0 ± 1.6, P = 0.096). Bowel function improved from before the operation to 3 weeks after surgery (10.7 ± 3.8 vs. 12.0 ± 3.2, P < 0.05), but then regressed to preoperative levels. Physical function worsened from before surgery (31.7 ± 6.2) to 1 week (27.5 ± 5.9, P < 0.0001), but surpassed preoperative levels at 3 weeks (33.5 ± 3.4, P < 0.01). Return to the activities of daily living occurred at 6.3 ± 4.7 days and work at 11.1 ± 9.0 days. Fatigue increased from before surgery (15.8 ± 6.2) to week 1 (20.7 ± 6.6, P < 0.0001) before improving at week 3 (14.0 ± 5.8, P < 0.01). Forty-four patients contacted the health care team 61 times before their 3 weeks appointment, most commonly for wound issues (26.2%), pain (24.6%), and gastrointestinal issues (24.6%). Seventy-two percent reported that the procedure had no negative effect on cosmesis at 6 months. Satisfaction with the procedure was high, averaging 9.52 out of 11. CONCLUSIONS: QoL is significantly affected in the 24 h after LC but returns to baseline at week 3. Cosmesis and overall satisfaction are high, and QoL improvements are maintained in the long term except for bowel function, which regresses to preoperative levels of impairment. Analysis of patient-initiated contacts after LC may provide feedback on discharge counseling to increase patient satisfaction.

Impact of the Society of Surgical Oncology-American Society for Radiation Oncology Margin Guidelines on Breast-Conserving Surgery and Mastectomy Trends.

BACKGROUND: In 2014, the Society of Surgical Oncology and American Society for Radiation Oncology guidelines defined negative margin for stage I and II breast cancer as "no tumor on ink." We hypothesized that repeat operation rates have decreased since the guideline introduction and would be associated with changes in overall surgical trends. STUDY DESIGN: The National Cancer Database was used to identify women who underwent initial breast-conserving surgery (BCS) for stage I and II breast cancer from 2004 to 2015. RESULTS: Of 521,578 patients that underwent initial BCS, 82.7% had BCS alone and 17.3% had repeat operation: 67% with BCS followed by another BCS, 24% with BCS followed by unilateral mastectomy, and 9% with BCS followed by bilateral mastectomy (BM). The repeat operation rate decreased from 16.2% in 2004 to 14.0% in 2015 (p < 0.01). Breast-conserving surgery with repeat BCS decreased from 12.8% to 9.7%, and BCS followed by BM increased from 0.7% in 2004 to 1.9% 2013, then decreased to 1.4% in 2015. Trends for all surgical patients regardless of initial procedure showed a BCS rate of 64.0% in 2013 that increased to 67.6% in 2015. The BM rate increased from 4.6% in 2004 to 13.6% in 2013, then decreased to 12.8% in 2015 (p < 0.05). Adjusted multivariable regression found independent predictors of repeat operation to be diagnosis before 2014 (odds ratio [OR] 1.25), age younger than 50 years (OR 1.70), Her2neu receptor-positive tumors (OR 1.61), and lobular histology (OR 1.61). CONCLUSIONS: Repeat operation rates are decreasing after 2014, which is also associated with a rise in BCS and decrease in BM rates. Dissemination of margin guidelines for early-stage breast cancer might be impacting overall surgical trends.

Survival rates for breast cancers detected in a community service screening mammogram program.

BACKGROUND: This single-institution long-term prospective study was performed in the setting of community service screening mammography to evaluate the association between the methods of breast cancer detection and survival rates. METHODS: From 1994 through 2001, data on 1237 patients with breast cancer were collected concurrent with definitive surgical treatment and entered into a comprehensive database. RESULTS: Mammography was the sole method of detection for 517 (44%) of 1179 Tis-T2 breast cancers. Fifty-seven percent of invasive cancers detectable by mammography alone were less than 1 cm in diameter. For 1049 patients with invasive cancers, the 5-year overall observed survival rates were 94% for 372 whose cancers were detectable by mammogram alone and 87% for 677 whose cancers were detectable by palpation (alone or in combination with mammography) (P = .0002). CONCLUSIONS: Most of the contribution to breast cancer mortality reduction is from the detection of small nonpalpable cancers, not from adjuvant therapy.

Failure of sentinel lymph node mapping in patients with breast cancer.

BACKGROUND: Lymphatic mapping with sentinel lymphadenectomy (SL) has become more widely used as an alternative to axillary dissection for the staging of breast cancer. This study was conducted to evaluate the potential associations of patient and tumor characteristics with the lymphatic mapping failure rate. STUDY DESIGN: Between September 1996 and April 2003, 1,094 breast cancer patients participated in a single-institution prospective SL protocol, which was conducted using technetium 99 m sulfur colloid alone to identify sentinel lymph nodes. During the validation phase, consisting of the first 80 patients, all patients had SL followed by axillary dissection. Beginning with the 81st patient, the standard technique consisted of radiolabeled colloid injection in a peritumoral distribution 16 to 24 hours before the operation, followed by SL alone for node-negative patients. RESULTS: Of 1,094 consecutive patients, 62 (5.7%) did not map. Patients having more than 10 involved lymph nodes had a significantly higher incidence of mapping failure (40.9%) than those who were node-negative (5.3%) (odds ratio = 9.19, p = 0.002). Age was a factor predictive of mapping failure for node-negative patients 70+ years of age (odds ratio = 3.14, p = 0.018). Biopsy technique, tumor size, tumor location, cell type, and surgeon experience were not predictors of mapping failure, regardless of node status. CONCLUSIONS: The lymphatic mapping failure rate was associated with both anatomic and pathologic factors. Patients with extensive nodal involvement had a significantly greater chance of mapping failure. Among node-negative patients, those who were older were more likely to have mapping failure than those who were younger, suggesting that decreased breast density in postmenopausal women might provide an anatomic explanation for nonmapping.

Single-incision results in similar pain and quality of life scores compared with multi-incision laparoscopic cholecystectomy: A blinded prospective randomized trial of 100 patients.

BACKGROUND: Our objective was to compare hospital charges and both perioperative and mid-term quality of life between single- (SILC) and multi-incision (MILC) laparoscopic cholecystectomy in a randomized controlled trial. METHODS: Patients with acute or chronic biliary disease were invited to participate. Pain scores, quality of life, and perioperative outcomes were measured. Patients were followed for 1 year postoperatively in the clinic with examination to document hernia formation. RESULTS: One hundred subjects were randomized to SILC (n = 49) or MILC (n = 51). Demographics were similar for both groups except more women underwent SILC (86% vs 67%, P = .026). Operative time was greater for SILC (63.5 ± 21.0 vs 43.8 ± 24.2 minute, P < .0001). Five SILC patients required added ports. One substantial complication occurred in SILC. Pain, the use of analgesics, and duration of hospital stay were equal between groups; however, charges were greater in the SILC group ($17,602 ± $6,089 vs $13,342 ± $8,197, P < .0001). Both groups reported similar quality of life and cosmesis. At an average follow-up of SILC (16.4 ± 12.1 months) and MILC (16.2 ± 10.5 months), no novel umbilical hernias were identified. CONCLUSION: SILC results in longer operative time and greater hospital charges with similar pain and quality of life scores compared with a standard laparoscopic approach.

Single-incision surgery has higher cost with equivalent pain and quality-of-life scores compared with multiple-incision laparoscopic cholecystectomy: a prospective randomized blinded comparison.

BACKGROUND: Since the development of single-incision surgery, several retrospective studies have demonstrated its feasibility; however, randomized prospective trials are still lacking. We report a prospective randomized single-blinded trial with a cost analysis of single-incision (SI) to multi-incision (MI) laparoscopic cholecystectomy. STUDY DESIGN: After obtaining IRB approval, patients with chronic cholecystitis, acute cholecystitis, or biliary dyskinesia were offered participation in this multihospital, multisurgeon trial. Consenting patients were computer randomized into either a transumbilical SI or standard MI group; patient data were then entered into a prospective database. RESULTS: We report 79 patients that were prospectively enrolled and analyzed. Total hospital charges were found to be significantly different between SI and MI groups (MI $15,717 ± $14,231 vs SI $17,817 ± $5,358; p < 0.0001). Broken down further, the following subcharges were found to also be significant: operating room charges (MI $4,445 ± $1,078 vs SI $5,358 ± 893; p < 0.0001); medical/surgical supplies (MI $3,312 ± $6,526 vs SI $5,102 ± $1,529; p < 0.0001); and anesthesia costs (MI $579 ± $7,616 vs SI $820 ± $23,957; p < 0.0001). A validated survey (ie, Surgical Outcomes Measurement System) was used to evaluate various patient quality-of-life parameters at set visits after surgery; scores were statistically equivalent for fatigue, physical function, and satisfaction with results. No difference was found between visual analogue scale scores or inpatient and outpatient pain-medication use. CONCLUSIONS: We show SI surgery to have higher costs than MI surgery with equivalent quality-of-life scores, pain analogue scores, and pain-medication use.

Sentinel node biopsy alone for node-positive breast cancer: 12-year experience at a single institution.

BACKGROUND: Complete node dissection for a tumor-positive sentinel node (SN) is becoming more controversial. We report our institution's 12-year experience with sentinel node biopsy (SNB) alone for a tumor-positive SN. STUDY DESIGN: This was a retrospective review from 1998 to 2009. Of 3,806 patients who underwent SNB, 2,139 underwent SNB alone, of which 1,997 were tumor-negative and 123 were tumor-positive. SNs were staged node-positive (N1mic or N1) according to American Joint Committee on Cancer criteria. RESULTS: One hundred and twenty-three node-positive patients underwent SNB alone with no completion axillary dissection for invasive breast cancer. Mean age was 57 years (range 32 to 92 years) and stage distribution was as follows: stage IIA: 76 (62%) patients; stage IIB: 40 (33%) patients; and stage III: 4 patients (3%). Mean size of the tumors was 1.9 cm (range 0.1 to 9 cm). Eighty-nine (72%) underwent lumpectomy and 34 (28%) underwent mastectomy. Ninety-three percent of patients underwent some form of adjuvant therapy. Forty-two patients (34%) did not undergo radiation and there were no axillary recurrences in this group. At median follow-up of 95 months, there has been 1 axillary recurrence (0.8%) and 13 deaths, 4 of which were attributed to metastatic breast cancer and the rest to non-breast-related causes. CONCLUSIONS: Axillary recurrence is rare after SN biopsy alone. This might be related to favorable tumor and patient characteristics and frequent use of adjuvant therapy.

The effects of hormone replacement therapy on postmenopausal breast cancer biology and survival.

BACKGROUND: The goal of this study was to compare the characteristics of breast cancers and survival rates in HRT users versus nonusers. METHODS: Data were analyzed for 1055 patients > or = 50 years of age who had definitive therapy for breast cancer from 1994 through 2002. RESULTS: There were 471 (45%) HRT users. The median age at diagnosis was 61.0 years for HRT users and 68.0 years for HRT nonusers (P < .001). HRT users more often had tumors that were <1 cm (P = .007), node negative (P = .033), and grade I (P = .016). HRT users had a decreased risk of death versus nonusers (hazard ratio = .438, 95% confidence limit = .263 to .729, P = .002). CONCLUSIONS: HRT users developed breast cancer at a younger age than nonusers; HRT use was associated with the development of biologically more favorable cancers than those that developed in nonusers; and overall and disease-free survival rates were higher in HRT users than nonusers.

A midpoint assessment of the American Cancer Society challenge goal to decrease cancer incidence by 25% between 1992 and 2015.

In 1998, the American Cancer Society (ACS) set a challenge goal for the nation to reduce cancer incidence by 25% over the period between 1992 and 2015. This report examines the trends in cancer incidence between 1992 and 2004. Trends were calculated using data on incident malignant cancer cases from the Surveillance, Epidemiology, and End Results (SEER) Registry. Delay-adjusted incidence trends for all cancer sites; all cancer sites without prostate cancer included; all cancer sites stratified by gender, age, and race; and for 20 selected cancer sites are presented. Over the first half of the ACS challenge period, overall cancer incidence rates have declined by about 0.6% per year. The greatest overall declines were observed among men and among those aged 65 years and older. The pace of incidence reduction over the first half of the ACS challenge period was only half that necessary to put us on target to achieve the 25% cancer incidence reduction goal in 2015. New understandings of preventable factors are needed, and new efforts are also needed to better act on our current knowledge about how we can prevent cancer, especially by continuing to reduce tobacco use and beginning to reverse the epidemic of obesity.
