Abstract
PURPOSE The study aimed at investigating prostate cancer patients' choice of androgen deprivation treatment (ADT) and possible factors that would affect their preferences of ADT. METHODS This was a single-centre cross-sectional study investigating the usage and preferences of ADT. Consecutives prostate cancer patients who were receiving injectable luteinizing hormone-releasing hormone (LHRH) agonist or antagonist were recruited from the prostate cancer clinic in a tertiary academic hospital. Patients who received bilateral orchidectomy or those who could not consent to the study were excluded. Disease characteristics, treatment information and patient background were documented. The survey collected information related to their change in ADT regimen, preferences on drug usage (routes and frequency of administration) and their reasons. A hypothetical set of three drug formularies was designed. Questions regarding patient preference and the contributing reasons raised in the format of questionnaire. RESULTS 100 patients completed the survey. Most patients started with more frequent injections (3-monthly, 54%; 1-monthly, 38%) and switched to 6-monthly injections (89%) at the time of the survey. Primary reasons for the change were healthcare opinion (72%) and less frequent treatment (51%). Three options of ADT (oral daily, 1-monthly and 6-monthly injection) with the same efficacies and side effect profile were offered: 61% preferred 6-monthly injection, 1% preferred 1-monthly injection and 38% preferred oral regimen. When patients were informed of lower cardiovascular side effects in 1-monthly injection or daily oral drug, patients' preference was 56% (6-monthly), 6% (1-monthly), and 39% (oral). Patients with polypharmacy (more than 5 regular medications) were more inclined to choose injections (p = 0.025). Patient age, educational background, employment status, marriage status and disease status were not found to be statistically significant contributing factors to patient preference. CONCLUSION 6-monthly ADT injection was the preferred ADT despite greater cardiovascular risks. Among 1-monthly or daily oral LHRH antagonist, more patients prefer oral option. Convenience factor was highly valued.

Abstract
PURPOSE Granular data on breast cancer (BC) are pertinent for surveillance, planning, and monitoring of cancer care delivery. We determined the trends in clinical presentation, management, and survival of women with BC in a multiethnic middle-income Asian setting over 15 years. METHODS Data of 7,478 Malaysian women newly diagnosed with invasive BC between 2005 and 2019 from three hospital-based cancer registries were included. Trends in demographic, tumor, and treatment characteristics were compared across period 1 (P1): 2005-2009, period 2 (P2): 2010-2014, and period 3 (P3): 2015-2019. Overall survival and net survival were determined. RESULTS More women in P3 than P1 were older than 60 years at diagnosis. Only a marginal increase in proportion of women with stage I disease was observed (23.7% v 27.2% in P1 and P3, respectively, P = .004). Nonetheless, patients were increasingly presenting with smaller tumors, fewer axillary node involvement, well-differentiated tumors, and hormone receptor expression in recent times. Proportion of women with human epidermal growth factor receptor 2 (HER2)-overexpressed tumors significantly decreased. Among indicated patients, receipt of anticancer therapies was somewhat similar over the calendar periods, except for neoadjuvant chemotherapy and anti-HER2 therapy, where increases in administration were noted. Significant improvements in survival were observed over the 15 years, particularly for HER2-overexpressed BCs. CONCLUSION Although the improvements in BC survival that we have observed validate ongoing cancer control efforts and treatment advances, study findings suggest that more could be done for earlier detection and improved access to effective therapies in our settings.

Abstract
The fear of cancer recurrence is cited as a motivator of women's preferences between routine monitoring and contralateral prophylactic mastectomy (CPM) as methods of managing ongoing breast cancer risk. We conducted a discrete choice experiment among a general community sample of women who completed 12 hypothetical choices between routine monitoring and CPM described by aspects of treatment efficacy, safety, cost and involvement in decision-making. Respondents also completed a modified cancer worry question to assess cancer concern. Approximately 57.5% of 464 women always chose one option, typically routine monitoring. The majority (71.5%) reported being concerned about cancer recurrence when completing choice tasks. Latent class analysis identified three groups: preferred routine monitoring; preferred CPM; and "traders" (willing to swap between options). Among traders, women were less likely to choose an option associated with higher risk of recurrence. Women were more likely to choose options associated with less-intrusive monitoring methods and where they were involved in decision-making. Women concerned about cancer recurrence were more likely to choose CPM over monitoring. This study shows that women's preferences about how to manage breast cancer recurrence risk reflect the importance of the associated health effects, experience of care and attitudes to cancer recurrence.

Abstract
PURPOSE The purpose of this study was to evaluate preferences for oral versus intravenous adjuvant chemotherapy among early breast cancer patients (UMIN-CTR number UMIN000004696). PATIENTS AND METHODS Eighty-two postmenopausal women with estrogen receptor-positive, human epidermal growth-factor receptor 2-negative breast cancer who had completed adjuvant chemotherapy were asked about their preferred route of administration of chemotherapy and the reason. Women also answered questions about their physical and psychological status and quality of life during chemotherapy. RESULTS Patients who had received oral chemotherapy preferred it more frequently than those who had received intravenous chemotherapy (100% versus 37%, respectively, chi-square =15.5; P<0.001). Patients who preferred the same route of administration of chemotherapy as they had previously received showed a significantly better psychological status during chemotherapy compared with those who preferred a different route. CONCLUSION Our study showed that preferences for oral and intravenous chemotherapy strongly depended on the actual prior administration of chemotherapy and patients' own experiences during chemotherapy.

Abstract
OBJECTIVE Fertility preservation is an important survivorship issue for women treated for breast cancer. The aim of this work was to examine the referral practices of health care professionals who treat women with breast cancer in the United Kingdom, and to investigate their understanding and knowledge of the fertility preservation options available. METHOD An invitation to participate in a confidential, online questionnaire was e-mailed to surgeons, oncologists, and clinical nurse specialists who manage patients with breast cancer in the United Kingdom. RESULTS n = 306 respondents. Factors which influenced whether fertility preservation options were discussed with a patient included the following: patient's age (78%), final tumor/nodes/metastasis status (37.9%); concern that fertility preservation would delay chemotherapy (37.3%); whether the patient had children (33.5%) or a partner (24.7%); estrogen receptor expression (22.6%), lack of knowledge regarding the available options (20.9%); and concern that fertility preservation would compromise the success of cancer treatment (19.8%). Twenty-seven percent did not know whether fertility preservation was available for their patients on the National Health Service. Nearly half (49.4%) of respondents said that gonadotropin-releasing hormone agonists were used for fertility preservation outside the setting of a clinical trial. Knowledge regarding the available options varied according to different members of the multidisciplinary team, with consultant oncologists better informed than consultant surgeons or clinical nurse specialists (p < .05). CONCLUSIONS Many health care professionals have incomplete knowledge regarding the local arrangements for fertility preservation for patients with breast cancer. This may result in patients receiving inadequate or conflicting information regarding fertility preservation.

Abstract
BACKGROUND There is very limited information about the amount of information that cancer patients retain after a fertility preservation (FP) consultation (FPC). Our objective was to assess patients' knowledge following FPC and to examine predictors of increased knowledge. METHODS We conducted a multi-center, cross-sectional, web-based survey at academic IVF centers, including women aged 18-43 years seen for comprehensive FPC between April 2009 and December 2010. The primary outcome measure was a knowledge score designed to assess comprehension of FP options. Analysis was performed to assess which patient variables were associated with higher knowledge scores. A 13-item knowledge tool about FP was developed (Kuder-Richardson 20=0.64). RESULT(S) Among 90 eligible subjects, 66 were successfully contacted and 52 completed the survey (79% response rate). Participant's median age was 30.7 (interquartile range (IQR) 24.9-36.9) years and most were Caucasian, college graduates, nulliparous and in a committed relationship. The median knowledge post-FPC score was 6 (IQR: 5-9). Higher knowledge scores were associated with a college education, higher income, a primary diagnosis of breast cancer, additional contact with the FP specialist following the initial FPC and use of specific reference websites such as www.fertilehope.org. Parity, marital status and completion of FP treatment were not associated with knowledge scores. CONCLUSIONS FP knowledge following comprehensive FPC remains limited. Modifications to the current single visit FPC, such as a standard follow-up visit or additional educational tools, may be needed to improve patient comprehension of complex FP treatment options. Further research is needed to validate the knowledge scale in broader populations of cancer patients receiving FPC.

Abstract
Background Increased health care costs have made it incumbent on health-care facilities and physicians to demonstrate both clinical and cost efficacy when recommending treatments. Though studies have examined the cost-effectiveness of adjuvant goserelin with radiotherapy for locally advanced prostate cancer, few have compared the cost-effectiveness of adjuvant goserelin to adjuvant chemotherapy alone in premenopausal breast cancer. Methods In this retrospective study at one hospital, the records of 152 patients with stage Ia to IIIa ER + breast cancer who received goserelin or chemotherapy were reviewed. Survival analysis was assessed by the Kaplan-Meier method. Patients were interviewed to evaluate their quality of life using the European Organization for Research and Treatment Quality of Life questionnaire (EORTC-QLQ-C30, version 4.0), and to obtain the utility value by the standard gamble (SG) and visual scale (VS) methods. Total medical cost was assessed from the (National Health Insurance) NHI payer's perspective. Results Survival at 11 years was significantly better in the groserelin group (P < 0.0012). The lifetime lost was lower in the goserelin group (42 months vs. 66 months). The quality adjusted survival (QAS) of patients who received goserelin was longer (122.5 ± 6.3 vs. 112.2 ± 6.7 months). Total expenses of goserelin were more than cyclophosphamide, methotrexate, 5-fluorouracil (CMF) or 5-fluorouracil, epirubicin, cyclophosphamide (FEC) chemotherapy regimes, but less than docetaxel, epirubicin (TE) or docetaxel, epirubicin, cyclophosphamide (TEC) regimes. The quality-adjusted life-year was higher in the goserelin group. Conclusions Goserelin therapy results in better survival and higher utility-weighted life-years, and is more cost-effective than TC or TEC chemotherapy.

Abstract
Breast cancer is the most common malignant tumor in women. Increasing survival rates after breast cancer, new reproductive techniques and growing interest regarding the quality of life after cancer have brought the possibilities of fertility-preserving treatment to the center of attention of oncologists and affected patients. Many of these women suffer from infertility and premature menopause as a result of chemotherapy. Several measures, for example gonadotropin-releasing hormone analogs, hormonal stimulation to cryopreserve oocytes, ovarian tissue cryoconservation or a combination of the methods, can be undertaken depending on the hormone receptor status of the tumor, and the patient's age and partner status. Embryo cryopreservation is currently the most promising fertility preservation option. Early counseling on fertility-preserving strategies is of utmost importance, so that the fertility-preserving method can be integrated into the oncologic therapy regime.

Abstract
Adjuvant treatment with aromatase inhibitors (AIs) improves outcomes in postmenopausal women with hormone-sensitive early breast cancer compared with tamoxifen. However, AIs should not be used in premenopausal women because they can paradoxically increase estrogen secretion and may therefore stimulate tumor progression. In perimenopausal women undergoing treatment for breast cancer, it can be difficult to determine true menopausal status because adjuvant chemotherapy, tamoxifen, and gonadotropin-releasing hormone analogues can induce transient (or permanent) ovarian suppression. How can one determine whether these women are truly postmenopausal and therefore candidates for AI therapy? A panel of experts in the field of endocrine therapy in breast cancer met in Dubrovnik, Croatia, on October 23, 2006, to discuss this clinical dilemma. This report summarizes the conclusions and recommendations that arose from this discussion.

Abstract
We report an open-label, prospective, crossover study involving 184 post-menopausal women experiencing hot flushes on adjuvant tamoxifen (T). Six weeks after switching to an AI, the primary end point, hot flush score, improved by 47.3% (P<0.001) compared to those reported on T. The mean mood rating scale (MRS) score improved by 9.7% (P=0.01). The total mean combined FACT (b+es) score improved from 134.2 (95% CI +/-2.96) to 143.5 (95% CI +/-2.96 <0.001), and the endocrine subscale improved by 9.8% from 51.73 (95% CI +/-1.38) to 57.34 (CI +/-1.38, P<0.001). At 6 weeks, significantly more women chose to remain on an AI: 133 (72%), vs 40 (22%) (P<0.001) preferring T. At 3 months, 107 (58%) preferred to remain on an AI, 55(30%) on T, and 22 (12%) withdrew. The overall arthralgia rate at 3 months was 47% on AI and 30% on T (P=0.001). In all 182 (99%) women reported appreciating the opportunity to experience both drugs. These data suggest that if patients suffering significant adverse effects on T are given the opportunity to try an AI, this empowers them to prioritize relative side-effects, improving wellbeing in a significant proportion. These data also highlight the need for hospital follow-up in this intolerant cohort.

Abstract
Adjuvant chemotherapy and hormonal therapy reduce the risk of recurrence and death due to breast cancer, but often at considerable cost to the health-related quality of life (HRQL) of patients. The short-term effects of chemotherapy on HRQL are well known and are accepted by most patients for modest gains in survival. The long-term effects of chemotherapy-induced menopause and hormonal therapy on HRQL are poorly recognized. Vasomotor symptoms and altered sexual function are common, distressing and inadequately treated. HRQL information is helpful in describing likely effects of adjuvant treatment, facilitating informed decision-making, identifying health problems to guide research into potential solutions, guiding treatment strategies for interventions with equivalent survival and guiding resource allocation. New technologies will make HRQL information increasingly available for individual patient care.

Abstract
Adjuvant tamoxifen therapy for 5 years reduces recurrence in hormone receptor positive, post-menopausal women with early breast cancer, but offers no advantage when prolonged to another 5 years, during which the risk of recurrence remains high. Treating patients, who remain disease-free after 5 years of tamoxifen, with letrozole significantly reduces recurrence, regardless of nodal status. This study evaluated the life-time cost-utility of extended adjuvant letrozole therapy in 62-year-old patients from a third-party payer perspective. A Markov model incorporated locoregional, contralateral, and metastatic recurrences. The comparator was placebo. Event rates were based on published trials. Utility values were taken from a clinical trial and published literature. Costs were obtained from published literature, provincial payment schedules, cancer agencies, and drug plans formularies. Resource use reflected Canadian treatment patterns. Robustness of the model was tested using deterministic and probabilistic sensitivity analyses. Extended adjuvant letrozole therapy of a cohort consisting of 50% node-negative and 50% node-positive patients prolonged their lives on average by 0.466 years or 0.267 quality-adjusted life years (QALYs) at an additional cost of Can$8,031 per patient, yielding an incremental cost-utility ratio (ICUR) of $34,058 per QALY. Letrozole was more cost-effective in node-positive than in node-negative patients (Can$26,553 vs Can$46,049 per QALY). Results were robust to variations in age, healthcare costs, and utilities. The degree of confidence that the cost per QALY would be below Can$50,000 reached 100% for node-positive and 77% for node-negative patients. Extended adjuvant letrozole is cost-effective in both node-negative and node-positive patients having ICURs below Can$50,000/QALY.

Abstract
BACKGROUND Ovarian ablation is an effective adjuvant therapy for primary breast cancer but little is known about its quality of life impact relative to the more widely used adjuvant chemotherapy. This randomized study compared quality of life outcomes of adjuvant ovarian ablation versus cyclophosphamide, methotrexate, fluoracil (CMF) chemotherapy. METHODS The Danish Breast Cancer Cooperative Group (DBCG) trial 89-b randomized premenopausal patients with receptor-positive, primary breast cancer between nine cycles of CMF chemotherapy given every 3 weeks and ovarian ablation by oophorectomy. In total, 317 randomized patients were invited to take part in a longitudinal quality of life study with assessments at 1, 3, 5, 9, 15, and 24 months after randomization. The questionnaire included the EORTC QLQ-C30, the Hospital Anxiety and Depression Scale, and additional items assessing potential symptoms not included in the standard instruments. RESULTS After 2 years, 260 women were alive and recurrence-free, and 196 of these (75%) had completed all six questionnaires. Overall, patients in the chemotherapy group had more symptomatology at the first three assessments (i.e., during the 6 months treatment period), except for hot flushes/sweats. There were few differences between groups at later assessments. In chemotherapy patients, the likelihood of preserving ovarian function decreased steeply with increasing age. CMF chemotherapy and ovarian ablation have similar impact on recurrence and survival. CONCLUSION Chemotherapy had more negative impact on health-related quality of life but preserved ovarian function in some younger patients.

Abstract
PURPOSE Recent clinical trials suggest that adjuvant ovarian suppression may be an equally effective and less toxic alternative to systemic chemotherapy in premenopausal women with hormone-responsive breast cancer. We used a decision-analytic framework to evaluate tradeoffs between efficacy and quality of life in the choice between these treatments. PATIENTS AND METHODS We used a Markov state-transition model to simulate clinical practice in a cohort of 40-year-old premenopausal women with newly diagnosed, hormone-responsive early breast cancer. We assessed three adjuvant treatments: chemotherapy, surgical ovarian suppression, and medical ovarian suppression. Outcomes were recurrence-free, overall, and quality-adjusted survival. Quality-adjusted survival reflected effects of cancer, treatment-related side effects, and menopausal symptoms. RESULTS Assuming equal efficacy, ovarian suppression was superior to chemotherapy when the relative utility of chemotherapy side effects compared with ovarian suppression side effects was less than 0.95. Results were sensitive to assumptions about the likelihood, duration and consequences of treatment-induced menopause. Treatment choice was affected by a 7% proportional increase in the efficacy of one therapy relative to the others, independent of other factors. CONCLUSION If adjuvant chemotherapy and ovarian suppression have similar efficacy, then there may be a subgroup of women for whom quality-of-life considerations dominate the choice of treatment. However, small differences in the relative efficacy of these therapies have a substantial impact on treatment choice, regardless of side effects and menopausal transitions.

Abstract
A structured review of studies on the health-economic evaluation of systemic adjuvant therapy for early-stage breast cancer was carried out. Of the eight articles that have been identified four were related to the cost-effectiveness of chemotherapy, three compared chemotherapy with combined chemotherapy and hormonal therapy and one compared tamoxifen (TAM) with third-generation aromatase inhibitors (ATIs). Results of the review indicate that the cost-utility of adjuvant breast cancer therapy is within the range of other oncological interventions. Adjuvant chemotherapy is most cost-effective in pre-menopausal women with node-positive breast cancer while cost-effectiveness decreases considerably with increasing age. Endocrine therapy with TAM is most cost-effective in ER-positive tumours with no significant age effect. The cost-utility of using the ATI anastrozole instead of TAM in adjuvant therapy cannot be conclusively assessed on the basis of the existing evidence.

Abstract
The acceptance of adjuvant treatment for early breast cancer (EBC) is dependent on the information that women are given about: available options, likely therapeutic gains, side effect profiles, convenience of treatment as well as their prior knowledge, experience and expectations. Acceptability in terms of adherence to treatment is then dependent on the actual burden experienced and the impact this has on quality of life (QoL). Studies show that >40% women do not adhere to tamoxifen because of side effects affecting QoL. The burden of adjuvant therapy may be underestimated by clinicians; thus, when options are discussed, treatments may appear more favourable and acceptable than they really are. The aim of the newer aromatase inhibitors (AIs) is to enhance efficacy without the associated unacceptable side effects. Interim results from the QoL sub-protocols of three trials, ATAC, IES and MA-17, provide useful indications of acceptability and the impact that AIs have on QoL. Data from patient self-report questionnaires and preference studies are needed to inform treatment recommendations and to aid the development of ameliorative interventions needed to accompany the most efficacious therapies.

Abstract
BACKGROUND Endocrine therapies for advanced breast cancer include tablets and intramuscular injections. When treatments have similar efficacy and tolerability profiles, addressing preferences about routes of administration is important. PATIENTS AND METHODS Two hundred and eight women>2 years post-breast cancer diagnosis were interviewed about their preferences for daily tablets or monthly intramuscular injections. Health-care professionals treating the women estimated patients' preferences. RESULTS Sixty-three per cent of patients preferred tablets, 24.5% preferred the injection and 12.5% had no preference. The most cited reasons for tablet preference were convenience and dislike of needles; for injection preference, adherence and convenience. Variables associated with preferences were body mass index, educational level, attitudes towards injections and efficacy perceptions. Estimates about patients' preferences by health-care professionals varied widely. When asked to imagine scenarios where injections produced fewer hot flushes, or where two injections monthly improved efficacy, injection preference increased to 60.6% and 74.5%, respectively. Disturbingly, approximately 50% of patients admitted they sometimes forgot or chose not to take their current oral medication. CONCLUSIONS The majority of breast cancer patients preferred hormone therapy via daily tablets rather than monthly injections. Information about side-effects or improved efficacy altered these preferences. Adherence to treatment cannot be assumed; patients' preferences about drug administration may influence this.

Abstract
The ninth St Gallen (Switzerland) expert consensus meeting in January 2005 made a fundamental change in the algorithm for selection of adjuvant systemic therapy for early breast cancer. Rather than the earlier approach commencing with risk assessment, the Panel affirmed that the first consideration was endocrine responsiveness. Three categories were acknowledged: endocrine responsive, endocrine non-responsive and tumors of uncertain endocrine responsiveness. The three categories were further divided according to menopausal status. Only then did the Panel divide patients into low-, intermediate- and high-risk categories. It agreed that axillary lymph node involvement did not automatically define high risk. Intermediate risk included both node-negative disease (if some features of the primary tumor indicated elevated risk) and patients with one to three involved lymph nodes without additional high-risk features such as HER 2/neu gene overexpression. The Panel recommended that patients be offered chemotherapy for endocrine non-responsive disease; endocrine therapy as the primary therapy for endocrine responsive disease, adding chemotherapy for some intermediate- and all high-risk groups in this category; and both chemotherapy and endocrine therapy for all patients in the uncertain endocrine response category except those in the low-risk group.

Abstract
BACKGROUND Adjuvant endocrine therapies such as tamoxifen, goserelin, and oophorectomy improve survival for premenopausal women diagnosed with early-stage breast cancer. However, these treatments often result in menopausal symptoms, sexual dysfunction, permanent infertility, or the need to delay pregnancy. We aimed to quantify the survival gains that premenopausal patients with early-stage breast cancer require to justify the side-effects and inconvenience of adjuvant endocrine treatments. METHODS Participants consisted of 102 women who had been diagnosed with early-stage (stage I-II) breast cancer 6-60 months previously, who were aged 40 years or younger at diagnosis, and who had been treated for a minimum of 3 months with endocrine therapy (67 with tamoxifen alone, seven with goserelin alone, and 28 with tamoxifen and goserelin or oophorectomy). 76 patients also received chemotherapy, and 75 received radiotherapy. Participants attended a face-to-face patient-preference interview, in which they were presented with four hypothetical clinical scenarios that were used to quantify the gains in survival rate and life expectancy that women judged necessary to make their endocrine therapy worthwhile. They also completed a questionnaire on standard psychological measures. FINDINGS About half of participants thought that adjuvant endocrine therapy was worthwhile for an absolute gain in survival of 2% from a baseline of either 65% or 85%, and for a gain in life expectancy of 3 months from a baseline of 5 years and of 6 months for a baseline of 15 years. Women who had had more severe endocrine side-effects required larger gains to make endocrine therapy worthwhile (univariate p=0.02, multivariate p=0.04). INTERPRETATION Modest gains in survival are sufficient to make adjuvant endocrine treatment worthwhile for premenopausal women with early-stage breast cancer. Knowing and incorporating what women think should enhance shared decision-making.

Abstract
Data from patient self-report questionnaires provide valuable information about side effects that patients may view as having a significantly detrimental impact on their quality of life and yet are not always recognised as important by healthcare professionals. Such information is very important in enabling patients to make informed choices regarding treatment options. Despite this, formal data collection from patient self-report assessments still fails to influence management decisions as much as traditional outcome measures such as disease-free survival, or clinician-recorded symptoms. There are now a number of different options for the treatment of patients with breast cancer. These include antioestrogens, aromatase inhibitors and oestrogen receptor antagonists for postmenopausal women, and chemotherapy and ovarian ablation (via oophorectomy, irradiation or with luteinising hormone-releasing hormone agonists) for premenopausal women. However, there are still surprisingly few published reports from comprehensive quality-of-life studies comparing such treatments and thus little is known about the relative impacts of each of these on quality of life. Here, the evolution of hormonal therapies for breast cancer is reviewed and the differences between the tolerability profiles of currently available treatment options are highlighted.

Abstract
The gastric mucosal surface was observed using the magnifying fibergastroscope (FGS-ML), and the fine gastric mucosal patterns, which were even smaller than one unit of gastric area, were examined at a magnification of about 30. For simplicification, we classified these patterns by magnifying endoscopy in the following ways; FP, FIP, FSP, SP and MP, modifying Yoshii's classification under the dissecting microscope. The FIP, which was found to have round and long elliptical gastric pits, is a new addition to our endoscopic classification. The relationship between the FIP and the intermediate zone was evaluated by superficial and histological studies of surgical and biopsy specimens. The width of the band of FIP seems to be related to the severity of atrophic gastritis. Also, the transformation of FP to FIP was assessed by comparing specimens taken from the resected and residual parts of the stomach, respectively. Moreover, it appears that severe gastritis occurs in the gastric mucosa which shows a FIP. Therefore, we consider that the FIP indicates the position of the atrophic border.
