Breast cancer in the elderly.

OBJECTIVE/METHODS: To determine the clinical behavior and outcome of breast cancer in the elderly, a series of 184 women older than age 69 years who received treatment for locoregional breast cancer at The University of Texas M. D. Anderson Cancer Center between 1976 and 1985 were studied for a median of 80 months. RESULTS: The results indicate that elderly women can tolerate standard surgical therapy and survive disease-free for many years; the breast cancer-specific survival rate of patients in this study was 79% at 7 years. Although 33% of patients had stage I disease, only 10% underwent breast conservation surgery. Despite 46% of patients having stage II and 21% having stage III breast cancer, fewer than 13% received systemic adjuvant therapy. Noncompliance with breast screening guidelines was evident in that only 3% of patients had tumors detected by routine screening mammograms and only 12% by routine physical examinations. CONCLUSIONS: Women with breast cancer should be informed of treatment options and the advantages and disadvantages of each choice based on physiologic rather than chronologic age.     

Management of stage III primary breast cancer. An analysis of 221 cases]

From Jan. 1978 to Dec. 1987, 221 patients of stage III breast cancer were treated by surgery combined with adjuvant chemotherapy and/or radiation therapy. The overall 5-year survival rate was 50.4%. The 5-year survival rate in patients with negative lymph node was 72.3% as compared with 37.5% in patients with more than 7 lymph nodes involved (P < 0.05). In patients who received postoperative adjuvant chemotherapy, the 5-year survival rate in premenopausal or postmenopausal group was 62.1% and 41.4% respectively (P < 0.05). The regional lymph node recurrence rate was 4.0% in patients who received postoperative radiotherapy as opposed to 9.6% for those without radiotherapy postoperatively. The distant metastasis rate was 19.1% in lymph node negative group as compared with 45.9% in patients with more than 7 lymph nodes involved (P < 0.05). To decrease the distant metastasis will improve the survival rate in the treatment of breast cancer. We believe that preoperative chemotherapy combined with radical surgery and postoperative adjuvant therapy may improve the survival rate in stage III breast cancer.     

Trends in Post‐Mastectomy Reconstruction in an Asian Population: A 12‐Year Institutional Review

Post‐mastectomy breast reconstruction is an integral component of breast cancer treatment. It is often perceived that women in Asian countries have a lower rate of post‐mastectomy reconstruction than Western populations. This study describes trends in timing and types of breast reconstruction performed in the largest healthcare provider in Singapore, over a period of 12 years. It also reports on the oncological outcomes and surgical safety. A retrospective review of all patients who underwent post‐mastectomy reconstruction from January 2001 to December 2012 at the National Cancer Centre Singapore and Singapore General Hospital was performed. Six hundred and twenty post‐mastectomy reconstructions were performed in 579 patients. The proportion of reconstructions increased from 4% in 2001 to 18% in 2012. Younger patients (<50 years old) and those with early stage cancer were more likely to undergo reconstruction. Immediate breast reconstruction was favored by more than 90% of patients. Postoperatively, 9% developed acute surgical complications that were treated surgically; 6% had additional surgery for late complications. Only 4% had delay of adjuvant chemotherapy. At median follow‐up of 63 months (range 3–166), loco‐regional recurrence was 4%, and distant metastases 8%. Post‐mastectomy reconstruction for breast cancer is increasingly performed in our institution. Both younger age and lower stage disease were associated with choice for reconstruction in our study. Low rates of delay to adjuvant therapy were noted, and it may safely be offered to suitable women undergoing mastectomy.     

A prospective study of adjuvant surgical resection after chemotherapy for limited small cell lung cancer. A University of Toronto Lung Oncology Group study

Seventy-two patients with limited small cell lung cancer were identified as candidates for adjuvant operation after chemotherapy. All patients received preoperative chemotherapy with cyclophosphamide, doxorubicin HCl (Adriamycin), and vincristine, or the epipodophyllotoxin derivative VP-16 and cisplatin. The rate of response to chemotherapy was 80% (complete response 38% and partial response 42%). After chemotherapy, 57 patients (79.1%) were candidates for adjuvant surgical resection, but only 38 underwent thoracotomy. Eight required a pneumonectomy, 25 a lobectomy, and five patients had no resection. Postoperative pathologic study revealed only small cell lung cancer for 29 patients, mixed and non-small cell lung cancer for two, non-small cell lung cancer for four, and no residual tumor in three patients. Pathologic staging revealed seven patients in stage I (N0), nine in stage II (N1), and 22 in stage III. The median survival time for the 38 surgical patients was 91 weeks and projected 5-year survival rate 36%. Patients with pathologic stage I disease had significantly longer survival times (median not reached) than did patients in stage II or stage III (median survival 69 and 52 weeks, respectively). Within the group not undergoing operation, 19 patients responded to therapy and were eligible for adjuvant surgical resection, but did not undergo thoracotomy (10 patients were randomized to radiation only, and nine patients refused operation). Their median survival of 51 weeks was inferior to that of the 38 surgical patients (p = 0.049). Adjuvant surgical resection after chemotherapy resulted in long-term survival and cure for a significant proportion of patients with pathologic stage I disease. A significant improvement in survival could not be documented for patients in stages II and III. Intensive pretreatment investigation including mediastinoscopy is essential to exclude patients who will not benefit from adjuvant surgical resection.     

Survival from primary breast cancer after routine clinical use of mammography

Clinical trials indicate that mammography provides a substantial breast cancer survival benefit; however, there is a need to demonstrate that this benefit extends to clinical practice and to determine the extent that current reductions in mortality are attributable to regular screening or adjuvant systemic therapy. Mammography was used routinely at our institution across a broad age range, in an era when most patients received no adjuvant systemic therapy. We examined breast cancer survival for a cohort of 678 stage I-III primary invasive breast cancer patients accrued from 1971 to 1990, and followed to 1996; 18% received adjuvant hormonal therapy and 15% received adjuvant chemotherapy. There were 61 women less than 40 years old; 136, 40-49 years; 341, 50-69 years; 140, > or =70 years. Factors available for multivariate investigations were age (years), tumor size (cm), nodal status (N-, Nx, N+), ER (fmol/mg protein), PgR (fmol/mg protein), adjuvant radiotherapy (no, yes), adjuvant hormonal therapy (no, yes), and adjuvant chemotherapy (no, yes). Forward stepwise multivariate regression with log-normal survival analysis was used to examine the effects of these factors on disease-specific survival. Ten-year survival by tumor size was adjusted for the effects of other significant factors. For women less than 40 years of age, 10-year survival at the T1a, T1b, T1c, and T2 cut-points for tumor size is, respectively, 0.77, 0.74, 0.67, 0.44; for 40-49 years it is 0.92, 0.90, 0.85, 0.62; for 50-69 years it is 0.81, 0.79, 0.75, 0.62; for > or =70 years it is 0.84, 0.81, 0.73, 0.44. With routine use of clinical mammography and up to 26 years of follow-up, we found breast cancer survival to be significantly better (p< or = 0.05) for all women with smaller tumors and that survival indicated a change in natural disease history with early detection. The Canadian National Breast Screening Study (NBSS) controls had significantly smaller tumors (p < 0.001) than our patients, which may indicate access to mammography outside of the NBSS that reduced the apparent survival benefit for clinical trial mammography.     

Validation of the AJCC 8th prognostic system for breast cancer in an Asian healthcare setting

AimsWe aim to validate the AJCC 8th edition prognostic staging system for breast cancer in an Asian setting.MethodsClinico-pathologic information and cancer-specific survival (CSS) outcomes of 6287 stage I to III patients with invasive breast cancer who underwent upfront surgery at SingHealth institutions in Singapore from 2006 to 2014 were analyzed. Survival distributions for the different staging systems were estimated by the Kaplan-Meier method and compared using the log-rank tests. Multivariable Cox proportional hazards models were used, with Akaike Information Criterion (AIC) and Harrell's Concordance Index (C-index) to compare both staging systems.Among patients with positive hormone-receptor status, 84.8% received endocrine therapy. Among the cohort, 60.3% of received chemotherapy; 82.1% of node positive patients received chemotherapy and 86.0% of HER2-enriched patients in whom chemotherapy was also indicated received adjuvant HER2-targeted therapy. Ninety-seven percent of patients received anthracyclines and/or taxanes containing chemotherapy regime.ResultsThe median follow up was 64 months. 2921 patients (46.5%) were discordant between the anatomic and prognostic systems of which 363 (5.8%) were upstaged and 2558 (40.7%) were down-staged. For all patients, stages in both the prognostic and anatomic systems were discriminating for 5-year CSS. Controlling for age, ethnicity and receipt of chemotherapy, the prognostic staging system model (AIC = 7538.87, C = 0.79) presented slightly better explanation and concordance of survival times than the anatomic staging system model (AIC = 7607.31, C = 0.77).ConclusionThe prognostic staging system was better than the anatomic staging system in predicting outcomes but the anatomic system remains relevant due to its ease of use.

Breast carcinoma in women 35 years of age or younger.

The relationship of the age at diagnosis and prognosis in breast carcinoma remains controversial. A widely held perception is that the disease has a particularly unfavorable prognosis in young women. To examine this question we have studied 166 women treated for primary operable breast carcinoma who were 35 years of age or younger at the time of diagnosis. Groups of patients treated consecutively in each of two time periods nearly a decade apart (1964-1970 and 1976-1979) have been studied. Differences between the patient groups in primary surgical treatment and postoperative adjuvant therapy were characterized in the 1970s by the increasing use of modified radical mastectomy and replacement of postoperative radiation therapy by systemic adjuvant chemotherapy. A trend to earlier stage of disease was found among patients treated in 1976 to 1979, but 5-year recurrence and survival rates were not significantly different from those of young women treated in the 1960s. Comparison of Stage II patients treated in 1964 to 1970 with postoperative radiotherapy with comparable women given adjuvant chemotherapy from 1976 to 1979 revealed no significant difference in disease-free survival in the first 3 years after surgery. It remains to be seen whether these changes in therapy will diminish the frequency of recurrences after 5 years, leading to an improvement in overall survival. When compared with historical controls from this and other institutions, the 5-year and 10-year survival rates of approximately 75% and 60%, respectively, found in this study of young women with primary operative disease were not appreciably different from those of women treated for breast cancer at a later age when the disease is more common.     

Breast cancer survival and perioperative blood transfusion

The effect of perioperative blood transfusion on disease-free and overall survival was studied in 812 patients with stages I and II breast cancer, followed up prospectively in a multicenter study. All patients initially underwent a modified radical mastectomy. Patients with axillary node-negative, stage I cancer were followed up without additional therapy. Patients with axillary node-positive, stage II cancer were randomized to receive adjuvant chemoendocrine therapy. Transfusion was done in 35.8% of the patients with stage I and in 37.3% of the patients with stage II cancer. For the patients with stage II cancer, perioperative blood transfusion did not affect disease-free or overall survival. For the patients with stage I cancer, perioperative blood transfusion resulted in a worse disease-free and overall survival (p = 0.05 and 0.02, respectively), which was particularly evident for those patients who received more than 1 unit. This study suggests that stage of disease, adjuvant therapy, number of transfusions, and duration of follow-up must be considered in further analyses.     

BREAST CONSERVATION: LONG-TERM RESULTS FROM WESTMEAD HOSPITAL

Background : Breast conservation has been shown to be a safe and effective alternative to mastectomy in early-stage breast cancer. The present study reviews the long-term outcome and toxicity after treatment of early breast cancer by conservative surgery and radiation. Methods : Between November 1979 and December 1989, 438 patients with Union Internationale Contre le Cancer (UICC) stage I or II breast cancer were treated with conservative surgery and radiation therapy (CS + RT) at Westmead Hospital. Surgery to the breast varied from a local excision to a quadrantectomy, depending on the preference of the referring surgeon. The axilla was surgically dissected in 299 patients (68%). All patients received postoperative breast irradiation. The whole breast was irradiated to 46–54 Gy (median dose, 50 Gy) using 6 Mev photons for 5–6.5 weeks. Boosts were given at the primary tumour site in 336 patients (78%), by electron therapy (88 patients), iridium-192 (247 patients) or photons (one patient). A total of 44 patients (10%) received adjuvant chemotherapy. Results : The median follow-up period for surviving patients was 84 months (range: 56–172 months). The 5-year actuarial rate of local recurrence was 6% (312 patients at risk), and the 10-year rate was 10% (52 patients at risk). Very young patients (aged 34 years at diagnosis) had a 5-year actuarial rate of local recurrence of 13% compared to 5% for older patients (P= 0.04). Neither the total dose to the primary site nor the boost technique influenced local recurrence. The 5-year freedom from distant relapse was 83%. The side effects included rib fractures (2%), symptomatic pneumonitis (3%), fatty necrosis or fibrosis requiring surgery (4%), and moderate-severe oedema of the arm (7%). Conclusions : The long-term data show that CS + RT for UICC stage I or II breast cancer results in low rates of local recurrence which are influenced by age at diagnosis, but not by radiation dose or boost technique. These results confirm those of other international series that CS + RT is a safe alternative to mastectomy for most women with operable breast cancer.     

Metaplastic breast cancer: clinical features and outcomes

Metaplastic carcinoma of the breast, a neoplasm with both epithelial and mesenchymal elements, represents less than 1 per cent of all breast cancer. We reviewed the records of all patients diagnosed with localized metaplastic breast cancer from 1991 to 2003 at our institution. We identified 21 patients. Mean primary tumor size was 4.62 cm. Eight patients (38%) had axillary node involvement at presentation. All the tumors were high grade. Only two (10%) of the tumors were hormone receptor positive. Seventeen (81%) of the patients received adjuvant chemotherapy, and 12 (57%) of the patients received radiation. Ten (29%) patients suffered a local recurrence. With a mean follow-up of 46 months, the 5-year disease-free and overall survival was 42 per cent (95% CI: 20% to 65%) and 71 per cent (95% CI: 46% to 96%), respectively. Stage-specific overall survival was 100 per cent, 83 per cent, and 53 per cent for stages I, II, and III, respectively. By multivariate analysis, there was no impact on recurrence or survival with regard to size, age, menopausal status, nodal status, histologic subtype, adjuvant therapy, or extent of surgery. Metaplastic breast cancer is a unique neoplasm that tends to present at an advanced stage and has a propensity for local recurrence. When stratified by stage, however, survival appears similar to that of adenocarcinoma of the breast, and these tumors should be treated as such.     

Surgical treatment for limited small-cell lung cancer. The University of Toronto Lung Oncology Group experience.

Since 1977, 119 patients with limited small-cell lung cancer have undergone combined modality therapy including surgery at our institution. Seventy-nine patients (58 male, 21 female; median age 63 years) had surgery first, and 67 of these had adjuvant chemotherapy. Forty (27 male, 13 female; median age 59 years) had chemotherapy first, and 94% had a complete or partial response before the operation. Pretreatment staging revealed 69 stage I, 27 stage II, and 23 stage III tumors. Twenty-six patients required pneumonectomy, 88 lobectomy, and five had no resection. Four patients had gross and six had microscopic residual disease. Postoperative pathologic examination showed small-cell lung cancer only (n = 95), non-small-cell lung cancer (n = 3), mixed (n = 17), and no residual tumor (n = 4). Postoperative staging revealed 35 stage I, 36 stage II, and 48 stage IIIa tumors. The median survival of the entire group is 111 weeks and the projected 5-year survival rate is 39%. No survival difference was seen between patients treated with chemotherapy before the operation and those undergoing an initial operation followed by chemotherapy (p = 0.756). The median survival for patients with pathologic stage I disease has not been reached, and the projected 5-year survival rate is 51%. This is significantly better than for the patients with stage II (median 82 weeks, p = 0.001) or stage III (median 83 weeks, p = 0.001) disease, who have projected 5-year survival rates of 28% and 19%, respectively. Seven of the 12 patients who had no adjuvant chemotherapy remain alive at 6 to 48+ months. Sixty-seven patients have died (11 had no evidence of disease). Only 10 patients had a relapse in the primary site alone, seven at the primary and distant sites, and 39 only in distant sites. In summary, resection improves control at the primary site, and a significant proportion of patients with stage I (N0) disease achieve long-term survival and cure with combined modality therapy including surgery. Stage II and IIIa patients have survival predictions similar to stage IIIa non-small-cell lung carcinoma treated surgically.     

Prognosis in Women with Breast Cancer and Private Extra Insurance Coverage

Background

Many women covered by the Spanish public health system also have an extra private insurance policy for gynecological examinations and routine annual mammography. We retrospectively analyzed the long-term survival rates in these patients when diagnosed with breast cancer.

Methods

We analyzed the survival and prognostic factors in patients diagnosed with breast cancer who were referred to a medical oncology unit for multidisciplinary treatment covered by private health insurance.

Results

Between 1994 and 2009, a total of 434 patients with breast tumor were analyzed: 33 in situ and 401 infiltrating. Among the infiltrating carcinomas, 38 were stage IV and 363 were stage I, II, or III. With a median follow-up of 62 months, the 5-year global survival rate was 91 %: 97 % for stage I, 94 % for stage II, and 77 % for stage III tumors. In the patients diagnosed by routine mammography, the 5-year survival rate was 96 %, compared with 86 % in those consulting their gynecologist after breast self-examination or for other symptoms (p = 0.0159). Seventy-four percent were treated conservatively and experienced better survival than the 26 % who underwent mastectomy (p = 0.0024). Patients with disease with positive hormone receptors had a better survival rate (p = 0.0264); hormone receptor status was the only independent prognostic factor in the Cox multivariate analysis. Postmenopausal patients who received adjuvant tamoxifen plus exemestane had a better prognosis than those who received tamoxifen alone (p = 0.0203).

Conclusions

Long-term survival rate was high in breast cancer patients with extra private insurance coverage. This is probably because disease was diagnosed at an early stage.     

Long-term results with resection of radiation-induced soft tissue sarcomas

INTRODUCTION: Radiation therapy is increasingly used as adjuvant treatment of many childhood and adult malignancies. Radiation-induced sarcoma is a well recognized if uncommon event. The objective of this study is to determine the prevalence and long-term outcome for patients who develop radiation-induced sarcomas. METHODS: From July 1982 to December 2001, 4884 adult patients with sarcoma were admitted and treated at our institution and recorded in a prospective database. There were 123 (2.5%) patients who had radiation-induced soft tissue sarcomas. Survival was determined by Kaplan-Meier analysis. Patient, tumor, and treatment characteristics were tested for their prognostic significance by log rank and the Cox proportional hazards model. RESULTS: The median interval between radiation and development of sarcoma was 103 (6 to 534) months. In 114 patients with radiation-induced sarcoma who underwent curative resection, the 5-year actuarial survival was 41%, with a median survival of 48 months at a median follow-up of 36 months for survivors. The most common malignancy for which radiation was used was breast cancer (29%), followed by lymphoma (16%) and prostate cancer (15%). Malignant fibrous histiocytoma (23%) was the most common histologic diagnosis, followed by fibrosarcoma (15%) and angiosarcoma (15%). High-grade tumors (n = 85; 79%), age > 60 years (n = 61; 50%), and gross positive resection margin (n = 36; 32%) were predictive of poor sarcoma-specific survival on univariate and multivariate analysis. CONCLUSIONS: The increasing utilization of adjuvant radiation therapy, especially for early-stage breast cancer mandates long-term follow-up to detect radiation-induced sarcoma. Surgical resection remains the primary therapy, but 5-year survival remains approximately 40%.     

Radical surgery for gastric cancer in Singapore

This study was conducted to define the pattern and results of gastric cancer surgery in Singapore by reviewing the epidemological data from the Singapore Cancer Registry together with a review of a personal series of 182 patients operated on over a 14 1/2-year period. As in Japan and the West, the incidence of gastric cancer is decreasing in Singapore; it was 2.3% per year for men and 1.5% for women in the period 1968–1982. Nevertheless, the disease is still common and the respective age-standardized rates among the ethnic Chinese in Singapore of 37.3 and 15.4 per 100,000 per year remain higher than in the West but are only about half the rate observed in Japan. These rates in Singapore Chinese are also higher than those seen in the Chinese-Americans in the United States, but are lower than those of the Chinese of Shanghai, which suggests that lifestyle and diet influence the incidence of gastric cancer. In the series of 182 patients, gastric adenocarcinoma occurred in the antrum or body or the whole stomach in 78.5% and in the cardia in 21.5%. Presentation was late: stage I, 10%; stage II, 7.7%; stage III, 28%; and stage IV, 54.3%. Surgical resection was performed whenever technically possible (146 patients, 80%). In 86 patients, all macroscopic tumors were excised by a radical resection approximating the R₂ type of resection, with only one operative mortality. In the cohort of patients operated on more than 5 years ago for carcinoma of the antrum or body, 25 of 51 patients have survived 5 years; 30 patients had stage III disease and 12 of these are 5-year survivors. The results of the present series of advanced gastric carcinoma treated by radical resection outside Japan appears encouraging in terms of the low operative mortality and long-term survival.     

Intraarterial Adjuvant Chemotherapy after Pancreaticoduodenectomy for Pancreatic Cancer: Significant Reduction in Occurrence of Liver Metastasis

The clinical benefit of adjuvant chemotherapy in pancreatic cancer patients is still questionable. Phase II studies using radiochemotherapy based on 5-fluorouracil (5-FU) provided evidence of an increase in median survival times. Because palliative chemotherapy by celiac artery infusion (CAI) led to an increase in survival in pancreatic cancer, we treated 24 patients with adjuvant CAI following resection of the head of the pancreas for pancreatic cancer (21 patients with Union Internationale contre le Cancer (UICC) stage III, 2 with UICC stage II, 1 with UICC stage I). Catheters were placed angiographically into the celiac artery and remained there for 5 consecutive days. One cycle of chemotherapy consisted of mitoxantrone, 5-FU, folinic acid, and cisplatinum. This treatment was repeated five times at monthly intervals. CAI was well tolerated, and World Health Organization (WHO) grade III toxicities were observed in 8%; WHO grade IV was seen in none of the treatment cycles. Furthermore, we observed pain reduction in nearly all patients under CAI. Median survival times in patients who received CAI were 23 months for all patients, whereas in patients who did not receive adjuvant treatment the median survival was 10.5 months. With Kaplan-Meier regression analysis of the patients who were curatively resected (R0 resection) and received CAI, the overall 4-year survival was 54%, whereas in patients without CAI the 4-year survival was 9.5%. The occurrence of liver metastases in the CAI group went down to 17%. These results demonstrate that CAI is well tolerated, reduces the risk of liver metastasis, and increases the survival time of pancreatic cancer patients.     

Breast cancer recurrences in elderly patients after lumpectomy

Approximately half of breast cancers occur in women 65 years or older. Some studies suggest that breast cancer may be a more indolent disease in this group of patients. Debate exists over the appropriate treatment of these women as they are significantly underrepresented in breast cancer research studies. As a result of comorbid conditions and patient refusal many are often treated less aggressively than their younger counterparts. This study investigated the recurrence rate in elderly breast cancer patients who had undergone lumpectomy as their primary treatment at our institution. A chart review was conducted on breast cancer patients treated from January 1, 1995 through September 26, 2000 with lumpectomy performed at Wake Forest University Baptist Medical Center. Study criteria included female gender and age greater than 65 years, first incidence of breast cancer, no evidence of distant disease at presentation, and availability follow-up assessed by clinical examination and mammogram records. Clinical and pathological features and treatments were evaluated. The Cox proportional-hazards model, Fisher's exact test, and analysis of variance were used for statistical analysis. One hundred thirteen patients met study criteria. The stage distribution was as follows: stage 0 (T(IS)), 16 per cent; stage I, 56 per cent; stage IIA, 24 per cent; and stage IIB, 4 per cent. With a median follow up of 30 months six (5%) patients developed locoregional recurrence, four (4%) developed contralateral cancer, and two patients (2%) developed distant disease. Mean time to recurrence was 21 months. No patient has died of breast cancer, but one patient died of a second malignancy. Radiation therapy and tamoxifen decreased recurrence as compared with no adjuvant treatment or with adjuvant radiation only (P < 0.05). We conclude that patients treated with tamoxifen and radiation therapy had a significantly smaller risk of recurrences than those treated with lumpectomy only or those receiving radiation alone. This supports similar treatment patterns recommended for younger patients. Women over 65 years of age should be carefully evaluated for adjuvant therapy.     

Role of conservation therapy for invasive lobular carcinoma of the breast

Background: Invasive lobular carcinoma (ILC) accounts for 5% to 10% of all invasive breast cancers. Although breast conservation therapy using local excision and postoperative irradiation is a standard therapy for early invasive ductal breast cancer, the result of this strategy in ILC is not well documented. We sought to determine the rate of locoregional recurrence after breast conservation therapy in patients with ILC. Methods: A retrospective review of 74 patients with ILC treated with breast conservation therapy at The University of Texas M. D. Anderson Cancer Center (n=43) or The John Wayne Cancer Institute (n=31) between 1977 and 1993 was performed. Results: The median age of patients was 60 years, and median follow-up was 56 months (range 1 to 207 months). Thirty-nine patients had American Joint Committee on Cancer stage I disease, 30 had stage IIa disease, and five had stage IIb disease. All patients underwent surgical resection and postoperative radiation therapy. Twelve patients received postoperative adjuvant chemotherapy, and 27 patients were treated with adjuvant hormonal therapy. The 5-year actuarial locoregional recurrence rate was 9.8%, and the median time to recurrence was 77 months (range 41 to 113 months). Patients with positive or close (⩽1 mm) surgical margins were at increased risk for local recurrence on univariate analysis (p=0.034). Of the nine patients with breast recurrence, six underwent salvage therapy with total mastectomy and are disease free at the time of this writing, two patients died of distant disease, and one is alive with local disease at the time of this report. The 5-year disease-specific survival rate was 93.7%. Conclusions: Breast conservation therapy for ILC achieves locoregional control in the majority of patients. However, long-term follow-up of patients is important because many local recurrences following breast conservation therapy are late events.

Survival outcomes in pregnancy associated breast cancer: a retrospective case control study

Pregnancy-associated breast cancer (PABC) has been defined as breast cancer diagnosed during pregnancy or within one year of delivery. It is believed that after adjusting for age and stage, the 5-year survival rates are the same in both pregnant and nonpregnant women. We conducted a retrospective case-control study among patients treated at our institution between 1990 and 2005 to compare the 5-year survival outcomes for PABC with women treated for breast cancer who were not pregnant. Overall survival (OS) and disease-free survival (DFS) were estimated by the Kaplan-Meier method, and log rank tests were used to assess the associations between OS, DFS and pregnancy status, HER-2 status, ER/PR status, and family history. The median age was 33 years (range 24-42) for both groups. Twenty-two (55%) patients with PABC were ER/PR receptor positive compared with 20 (50%) for the controls. Ninety percent of patients with PABC received chemotherapy compared with 87.5% in the nonpregnant group. 91.5% of patients with PABC had breast-conserving surgery and 8.5% had mastectomies compared with 86% and 14%, respectively, for the control group. The median OS was 4.9 years in the PABC group compared with 6 years for the controls (p = 0.02). The median DFS was 2.7 years for the PABC group compared with 5.1 years for the controls (p = 0.01). The most common site of relapse was bone for the PABC group (27%) and local recurrence (33%) for the controls. Univariate analysis revealed that OS and DFS were associated with pregnancy status, family history, ER/PR status, and stage. After adjusting for age and stage, PABC patients had higher risk of both death (p = 0.01) and recurrence (p = 0.02) compared with nonpregnant controls. Women with PABC had significantly shorter OS and DFS compared with nonpregnant age and stage-matched controls.
