The present invention generally relates to diagnosis and/or monitoring systems, and more specifically, the present invention pertains to women's sanitary products embedded with cancer diagnostic and/or monitoring means.
Among the cancers that most often affect women are breast, colon, endometrial, lung, cervical, skin, and ovarian cancers. Ovarian Cancer is cancer of the ovaries, which are female reproductive organs that are similar to the testes in men. They produce the ova (eggs) that, when fertilized, develop into a fetus, and also generate the female sex hormones estrogen and progesterone. There are two ovaries, each of which is located within the pelvis beside the uterus.
When an ovary releases an egg, the egg follicle bursts open and becomes the corpus luteum. This structure needs to be repaired by dividing cells in the ovary. Continuous ovulation for a long time means more repair of the ovary by dividing cells, which might acquire mutations in each division, and may eventually lead to cancer.
Signs and symptoms of ovarian cancer are frequently absent in early stages, and even when they do exist, they may be subtle. This unfortunately leads in many cases to late diagnosis, having the cancer already spread and advanced into later stages. There is reason to believe that improved regular screening routines for ovarian cancer could lead to earlier diagnosis.
The risk of ovarian cancer increases in women who have ovulated more over their lifetime. This includes those who have never had children, those who begin ovulation at a younger age or reach menopause at an older age. Other risk factors include hormone therapy after menopause, fertility medication, and obesity. Ovarian cancer is more likely to occur as women get older. Women who have never had children, who have unexplained infertility, or who had their first child after age 30 may be at increased risk for this cancer. Women with a personal or family history of hereditary non-polyposis colon cancer (HNPCC), ovarian cancer, or breast cancer are more likely to have this disease.
About 10% of cases have been found to be related to inherited genetic risk; women with mutations in the genes BRCA1 or BRCA2 have about a 50% chance of developing the disease. Only one allele need be mutated to place a person at high risk, because the risky mutations are autosomal dominant.
If caught and treated in an early stage, ovarian cancer may be curable. Treatment usually includes some combination of surgery, radiation therapy, and chemotherapy. Outcomes depend on the extent of the disease and the subtype of the cancer present.
Several markers have been associated with women related cancer diagnosis and a few of which may be detected by diagnostic tests such as blood tests or feminine discharge extraction (for example in Van Gorp et al., “HE4 and CA125 as a diagnostic test in ovarian cancer: prospective validation of the Risk of Ovarian Malignancy Algorithm”, Br J Cancer. 2011; Leung et al., “Ovarian cancer biomarkers: current state and future implications from high-throughput technologies”, Adv Clin Chem. 2014; Di leva et al., “The Role of microRNAs in the Tumorigenesis of Ovarian Cancer”, Front Oncol. 2013).
Available tests are generally lab based and/or require clinical sample collection. For a woman to get tested she may need to actively turn to her physician and request a lab-based diagnostic test. Often a woman will request such a test only after having experienced at least some symptoms. Unfortunately, experiencing such symptoms often means it is already too late. For example, for women at risk, bi-yearly routine (serum CA-125) lab tests are often recommended. This test has not proven effective in early detection of ovarian cancer.

Women may be sensitive and/or resistant to clinical based gathering of vaginal secretion, included and/or especially during a non-menstrual phase. In some embodiments, the current invention facilitates easier clinic based and/or home-based gathering and/or testing of vaginal secretions. For example, the system may include an anatomical pad(s) for gathering vaginal secretions and/or a biomarker reader adapted for the pad. Optionally the system is configured for continuous use and/or home use. Management of the pad and/or testing may be adaptive, for example, based on baseline(s) adapted on personalized data
An aspect of several embodiments of the current invention relates to diagnosing and/or monitoring cancer in females based on indications of a physiologic marker in a female hygienic product. As used herein, the term “hygienic product” refers to any sanitary apparatus used in female hygiene routines, such as for a non-limiting example, sanitary pads, and/or tampons, and/or interlabial pads, and/or pantyliners, and/or sanitary napkins, and/or sanitary towel, and/or menstrual pad. The means and methods provided by some embodiments of the present invention utilize feminine discharge (also referred to as vaginal discharge) for an identification of at least one physiologic marker suggestive of a female-related cancerous condition. In some embodiments, vaginal discharges include cervical mucus. Alternatively or additionally, the vaginal discharges include vaginal fluid comprising fallopian secretions. In some embodiments, a female-related cancerous condition includes fallopian cancer. Alternatively or additionally, the cancerous condition includes ovarian cancer, and/or uterine cancer, and/or cervical cancer and/or breast cancer. In some embodiments, the physiologic marker is a non-cancerous indicator, used for example, as a positive control of the device detection system. As used herein, vaginal discharge does not include menstrual fluids.
In some embodiments, the current invention provides women with a self-operable solution, which is simple and easy to follow on a regular basis. This may facilitate more consistent screening than conventional solutions
In some embodiments, the current invention provides a self-diagnostic device easy to operate at the comfort of one's home and/or directed for early diagnosis of women-related cancerous conditions fulfills a long-felt need.
An advantage of using vaginal discharge which is not menstrual fluids for the detection of the physiologic marker is the ability to identify the physiologic marker at least once a day. In some embodiments, the physiologic marker is identified every few days, for example a week. In other embodiments the physiologic marker is identified at least once a month, but not on menstruation days when the vaginal fluids are diluted in the menstruation fluids.
Therefore, another advantage of using vaginal discharge which is not menstrual fluids is the surprisingly high concentration of the physiological markers, which are not diluted in the menstruation fluids, as shown in
In some embodiments, the hygienic device includes at least one absorption zone configured to accumulate vaginal discharges. In some embodiments, the absorption zone comprises a predetermined capacity for fluid accumulation. Optionally, a visual indicator is provided to indicate a full capacity, for example, a color change and/or an appearance or disappearance of a visual marker.
In some embodiments, vaginal discharges absorbed in the hygienic device are utilized to identify at least one physiologic marker related to a cancerous condition.

Optionally, a viscosity-reducing agent is utilized with the device to allow fluidizing of the vaginal discharges, in order to facilitate their utilization in the diagnostic system of the diagnosis device. As used herein, the term “viscosity-reducing agent” refers to any solvent, buffer or gel-like beads which in contact with a viscous fluid interact with it to provide a more liquefied formulation of the viscous fluid, resulting in fluid with reduced viscosity. In some embodiments, the viscosity reducing agent is embedded with the hygienic device prior to its hygienic use, for example, by a manufacturer of the hygienic device. Alternatively or additionally, a viscosity reducing agent is added to the hygienic device by the user, optionally following its hygienic usage. In some embodiments, the viscosity-reducing agent is made in contact with the discharges only after the discharges are sufficiently accumulated, and/or after a predetermined quantity of the discharges has been accumulated. In some embodiments, the viscosity reducing agent is a mucin dissolving agent. Alternatively or additionally, the viscosity reducing agent is a chemical composition. Alternatively or additionally, viscosity reducing enzymes are used. As used herein, the term “enzymatic activity” refers to a catalytic effect exerted by an enzyme, which could be in the form of a protein having enzymatic activity capacity and/or any other material contributing to the catalytic effect in a chemical reaction, and such aiding cofactors (for example magnesium, adenosine triphosphate and the like).
In some embodiments, the diagnostic device provides diagnostic results only by using the device at its main hygienic usage, and without adding additional functions by the user. Alternatively, the user needs to perform at least one more function following the hygienic usage of the device. For example, a user may wear a hygienic device for several hours, after which the device is removed, and a dissolving agent is added to the device.
An aspect of several embodiments of the invention relates to quantitative and/or relative assessment of a presence of a physiologic marker in female discharges. In some embodiments, a female hygienic device is configured to absorb vaginal discharges, identify at least one physiologic marker and accordingly visually indicate the presence of the physiologic marker. In some embodiments, each user establishes a baseline of the presence of the physiologic marker, for example by using the device for the first time, or by averaging a number of device usages. In some embodiments, an image analysis method is used to identify variations from the user's baseline. Optionally, a smartphone is used, having a processor with instructions for analyzing the variations. Alternatively or additionally, a tablet, and/or a personal computer are used. In some embodiments, the smartphone, or the like, alerts a caregiver once a variation is determined. Optionally, a threshold of the variation is predetermined for inducing an alert.
In some embodiments, quantitative assessment is provided by assessing the color intensity of an indicator. Alternatively or additionally, quantitative assessment is provided by assessing the number of indicators, for example, between 1 and 3 indicators, or between 1 and 5 indicators, or between 1 and 10 indicators. Alternatively or additionally, quantitative assessment is provided by assessing the shape of the indicator/s.
An aspect of some embodiments of the present invention enables high-risk women to specifically, and personally follow their own changes and/or progressions in their physiologic conditions, by means of a platform for at-home monitoring. In some embodiments, the system enables high-risk women to establish a personal baseline, which optionally serves as a reference value. In some embodiments, women periodically, for example once a month, test their current values and compare them to their reference values. Any change in biomarker concentration indicated by a change from the reference values would inform the woman she needs to proceed to a thorough check-up to find out the source of this rise.
In some embodiments, the hygienic diagnostic device is used for following up on post oophorectomy patients, optionally, as routine screening. It should be noted that post oophorectomy patients are extremely liable to develop relapse and, in some embodiments, the device is used with a high frequency, such as every month.
In some embodiments, the current invention relates to a semi quantitative detection unit for multi biomarkers and/or for a biomarker fingerprint/signature. Optionally, the biodetection device may allow quantification of the conditions for example employing a standard protein. Optionally, the detection unit may include a lateral flow device for sampling and/or testing. Optionally, detection may include immunodetection.
In some embodiments, a bio-detection device may use another immune-detection method. For example, the bio-detection device may use a standard protein and/or multiple biomarkers. For example, the bio-detection device may include a solid phase immune-detection method for example bead based.
In some embodiments, an immune detection assay may be used for biomarker quantitation. Optionally, one or more assays may be antibody-based for example using enzymatic, fluorescent and/or nano-particles platforms. Such platforms may include one or more of bead based assay, lateral flow based assays, and/or solid phase immunoassays (e.g. such as ELISA).
In some embodiments, a testing platform may include buffer. For example, a buffer may be used to control pH and/or concentrations of salts (e.g. electro-conductivity) of a sample. Optionally, a buffer may contain protease and/or Nucleic acid digesting enzyme (e.g. DNase, RNase) inhibitors. Optionally, a buffer may contain a stabilizing protein and/or a carrier protein. Optionally a buffer may contain a standard protein (for example facilitating quantitation). In some embodiments, a buffer may contain a detection antibody. In some embodiments, a buffer may contain one or more pairs of antibodies and/or beads according to the number and kind of analytes, for example to measure biomarker concentrations. Optionally a buffer may contain an antibody pair conjugated to detect a moiety (e.g. fluorescent/gold nano particles/enzymes). Optionally a buffer may contain primers for DNA/RNA detection.
In some embodiments, a vaginal fluid sampling and/or testing system may be configured to give consistent results under varying conditions. For example, the system may account for personal variations between subjects and/or temporal variations and/or variations in the state of a subject (e.g. breast feeding, mood, phase of menstruation cycle). For example, a sampling and/or testing method may include calculating the change between baseline and a specific measurement and, determining if this change is indicative for cancer presence. For example, an algorithm may be used predict the risk for ovarian cancer. The algorithm may use multiple test data and/or data measured over time and/or data about the individual and/or her state and/or data between different individuals. Optionally the algorithm will run on a personal computer of the user (e.g. a cell phone and/or a personal computer). Optionally the algorithm will use artificial intelligence. It may employ captured images of sampling and/or testing devices (e.g. the subject takes a picture and/or the algorithm interprets the picture). Alternatively or additionally, data storage and/or processing may be clinic based and/or network based. In some embodiments an algorithm will include data from personal data devices and/or network based data (e.g. cell phones, fitness equipment, gym records, smart watches, location services, weather services) to improve testing interpretation. An application on a personal data device (e.g. a cell phone) may collect and/or interpret and/or transmit data.
